Some vital tips to select the exact frame for your steel building

Before starting the design of any steel building, the type of frame perfectly suitable for the building should be chosen preliminary.

Steel buildings have good versatility and flexibility in frame design and application because of extreme strength to weight ratio of steel.

The strength and stability of steel helps in making a wide array of frame designs and styles to meet almost any requirement.

Given below, different types of frames for your steel building:

I-BEAM AND TAPERED BEAM: I-beam style frames are mostly recognized.

a. The frame is constructed with in-built plate sections connected together or from hot-rolled beams.
b. The "I" in I-beam originates from the cross-section of the beam that is shaped just like the letter that recognizes it.
c. The I-beam design is instrumental in building high-rise structures with highest strength and lowest material.


I-beam structures are also described as straight column buildings where the columns contain identical width across their length. The tapered beam belongs to a straight column rigid frame that expands the interior space.

The tapered beam is suitable for smaller buildings where clear spans are needed. A tapered beam building is easily divided into interior bays and is an optimal design for employing small crane support systems.

Tapered beam is also known as tapered column. The thicker end of the column is connected with the thicker end of the crossbeam at the joint among wall and roof, arranging an exceptionally strong joint at the eave. The narrow ends intersect at the roof line or expand to the ground.

The lower interior space is increased whereas the column is sufficiently strong to provide support for cranes and other equipment for passing items within.

OPEN WEB DESIGN: Open webs are also called as trusses. The web is developed with a top and bottom chord attached with diagonal angles. Open web design is a cost effective and perfect choice for clear spans of 250 feet and greater.

However, it is quite complicated to fabricate as compared to other designs.

Open web design facilitates you to integrate HVAC, wiring, and sprinkler systems directly into the truss framework, leaving the interior open and column-free.

Variations among Load bearing and framed structures

Superstructure is the section that situates over the ground. It comprises of walls, columns, beams, floors, roofs, doors, windows, lintels, staircases.

Types of super structures on the basis of load transmission

The super structures are categorized as follow :-

a. Load bearing structures
b. Framed structures


Load bearing structures:

Under this type of structure, the load on the structure is delivered in vertical direction through walls and then the wall transmits these loads and the self weight. These types of constructions are mostly found in residential buildings where the dimension of rooms is fewer. The residential buildings up to ground + 2 floors is constructed inexpensively with such structures.

Framed structures:

Under this type of structures, a frame work of columns and floors are constructed initially. Then the walls are erected to divide the living area.

The walls are dependent on self weight only. These types of structures are suitable when there are lots of stories in a building as well as when bigger areas should be covered free from walls.

Variations among load bearing and framed structures

Load bearing structure:

1. Construction cost is minimum
2. Best fit up to three stories
3. Walls are thicker and consequently floor area is curtailed.

4. Construction process is slow.
5. Once the construction is completed, it becomes difficult to modify the position of walls.


Frame structure:

1. The construction cost is higher
2. Ideal for different number of stories
3. Walls are thinner and as a result, more floor area can be utilized.
4. Rapid construction speed

5. If required, the location of wall may be modified.
6. Resistance to earthquake forces is good

Types of construction beams and their uses

Beams are the horizontal member of a structure as well as weight-bearing supports that carry transverse loads. Beams transmit all the loads along with its own weight to the columns or walls.

The posts and columns, belong to the vertical companions of the beam and provide strong support to maintain the structural integration for all types of buildings.

The beams are present in walls, floors, ceilings, roofs, decks and garages of any building. Given below, the basic characteristics of a beam.

I-Beams: I-beams are generally used in big commercial building projects, but they also construct houses, particularly interior walls.

The I-beams are generally arranged on top of foundation or basement walls to give support to the upper level of the house. They're frequently utilized in garages where they are utilized as tracks or rails for the motorized wheeled trolleys which open and close garage doors.

Flitch Beams: Steel fabrication companies produce flitch beams by coupling lengths of wood and metal jointly. The wooden section can be fixed to other structures, whereas the metal part offers extra strength.

The outcome is lighter than a steel beam but can carry adequate weight as compared to a wooden one. Flitch beams are specifically usable throughout renovations work where a load-bearing wall is eliminated.

Box Beams: Box beams are also called as box girders. Box beams are lengths of wood or steel which are attached at right angles to make something similar to a long, hollow box. Box beams are conventionally built up with wood, and three-sided box beams are commonly connected with ceilings to provide visual interest as well as support. Four-sided box beams are commonly used.

Hip Beams: Hipped roofs contain four sloping sides. The "hip" is where various roof sections intersect. The hip beams or rafters are necessary for these types of roofs.

Every hip beam supports various smaller pairs of beams that stretch from it. Wooden beams are conventional, but steel versions are gaining popularity since homeowners transform unfinished or obsolete attics and lofts into modern living spaces.

Cantilever Beams: The cantilever beams are useful for projecting house components like bay windows, balconies, roofs and canopies. As attached structures support them at just one end, cantilever beams appear to protrude from buildings.

A cantilever beam disperses its weight either at or along the unsupported segment of the beam.

Bond Beams: Bond beams are set inside masonry like stone, clay, brick or cement walls.

How does area conversion calculator work?

Area Conversion Calculator is used to convert units of area by providing the value to be converted to units.

Methods To Convert Units of Area: Conversions are done with the application of a conversion factor. By recognizing the conversion factor, converting among units turns out to be a simple multiplication issue:

S * C = E

Where S denotes the starting value, C denotes the conversion factor, and E denotes end converted result.

To convert from any unit into m2 easily, as for instance, from 50 ft2, just multiply with the value provided in the right column of the table below.

50 ft2 * 0.09290304 [m2 / ft2] = 4.645152 m2

To convert from m2 back into units in the left column divide with the value provided in the right column or, multiply with the reciprocal, 1/x.

4.645152 m2 / 0.09290304 [m2 / ft2] = 50 ft2

To convert between any units in the left column, suppose from A to B, it is necessary to multiply with the factor for A to convert A into m2 then divide by the factor for B to convert out of m2. Or, you can get the single factor as per your requirement by dividing the A factor with the B factor.

As for instance, to convert from ft2 to mm2 you would multiply with 0.09290304 then divide by 0.000001. Or, multiply by 0.09290304/0.000001 = 92903.04. So, to convert directly from ft2 to mm2, it should be multiplied with 92903.04.

To learn how to convert the units, follow this illustration. Suppose, it is required to convert from ft2 to m2; as you can multiply anything with 1 and still retain the original value, but in diverse units, set it up so that ft will cancel out leaving with m.

Since:
1 m = 3.28084 ft, 1 m / 3.28084 ft = 1

The conversion can be written as:
1 ft2 = 1 ft2 (1 m / 3.28084 ft) (1 m / 3.28084 ft) = 0.0929030 m2
And we now have our factor for conversion from ft2 to m2 as 1 * 0.0929030 = 0.0929030. Keep in mind that rounding errors occur in this value. The value in the table, 0.09290304, is more authentic.
Knowing that 1 ft2 = 0.09290304 m2, we can now obtain the conversion factor for converting back. By dividing both sides of the equation with 0.09290304, we get about 10.7639104 ft2 = 1 m2. So, the conversion factor to be multiplied to convert from m2 to ft2 is about 10.7639104.

Details about concrete compaction methods

Compaction stands for one of the crucial methods of concreting. By compaction, the air voids is dissipated from the concrete.

With the existence of air voids, the honeycomb in concrete is created and the strength of the concrete is reduced significantly. 1 % of air voids decrease the concrete strength roughly 6 %.

Either manual or mechanical process is undertaken for the compaction of concrete. Manual compaction is performed by hand devoid of applying any machines rather it is performed with tamping rods.

In mechanical compaction, the vibrators are used to make compaction.

METHODS OF COMPACTION OF CONCRETE: They are many factors consider for choosing compaction method is undertaken on the basis of several factors like reinforcement quantity and spacing, depth of concrete structure, nature of availability of machines, position of concrete structure, concrete paste consistency , form work difficulty.

Different Methods of compaction are given below :-

HAND COMPACTION METHOD: Hand compaction is performed with the following three methods namely Roding, ramming and tamping.

In Roding method a rod with 2 m length and 16 mm dia is utilized. The edge of the rod is sharp. Density of the concrete is 150 mm to 120 mm.

Compaction process is undertaken all through the concrete area. Compaction should be continued unless it becomes entirely compacted.

Another process is tamping. Under this process, the cross beam with dimension 10 cm x 10 cm is employed to compact the concrete. Compaction and concrete surface level is retained evenly. It is suitable for road pavement flooring concrete and roof concrete works.

Mechanical Compaction: In mechanical compaction process, vibration technology is mainly utilized. Vibration leads to temporary liquefaction and as a result reserved air among aggregates is eliminated instantly. In mechanical compaction different types of vibrators are applied which range from internal or needle vibrators, external vibrators, table vibrators, surface vibrator.

There should adequate compaction for concrete structure otherwise honeycomb (air voids) may occur in concrete and it can reduce the strength of concrete significantly.

Uses and benefits of concrete pumping

Concrete pumping is the latest technology applied in the modern construction industry to set the concrete in all the structures ranging from high skyscrapers to the slightest convenience store. With concrete pumping, it is possible to arrange the concrete where it requires to fit.

Concrete pumping is the most convenient method for pouring concrete through a machine to transmit the liquid concrete. Normally, two basic types of pumps are utilized in concrete pumping i.e. boom pump and line pump.

Boom pump – It is self-contained unit that comprises of the frame and a truck. It is mostly applied to pour concrete in high up or difficult to arrive at the location.

Line pump – It is a portable unit that can pump structural concrete along with mortar, shotcrete, grout, wet screeds and foamed concrete.

Given below, some useful benefits of concrete pumping :-

Huge savings in time - Time is significantly reduced as the time is only required for mixing concrete and delivering to proper location.

Besides, the crew doesn’t have to make way for concrete trucks to pour the concrete to all the various locations.

Greater Productivity – The concrete pumping allows the crew members to deal with other aspects of the project since they don’t require to utilize shovels and wheelbarrows for the purpose of shifting concrete where it requires to fit.

Higher Precision – As the concrete pump expands from the truck right to the proper location the concrete is required, the entire process is error-less and precise.

This precision helps with productivity, wasted concrete because of spillage and fewer times for cleaning up.

Curtailment in labor costs – Less workers are required to set up and utilize the concrete pump as compared to the standard method of executing things. As less workers are needed, the labor cost is also reduced considerably and a more gainful project is created for the builder.

Greater employee safety – The employees needed to drive the concrete pump remain safe as compared to the employees assigned to mix and move the concrete with the conventional method.

With concrete pumping, heavy lifting is not required and as concrete moves directly to the spot, it requires less possibility for mishaps that can lead to severe injury.

Applications of concrete pump:

Residential projects similar to walls, foundations and patios.
Agricultural projects similar to sheds, barns, silos and bunkers.
Civil projects like hydro stations, water treatment plants or bridges.
Commercial or industrial projects similar to high rise buildings, ice rinks, strip malls and factories.

Importance of soundness of cement

Cement is most recognized construction material. It is very useful for concrete, mortar, plaster, etc. Prior to apply cement for concrete construction, the quality of the cement should be checked thoroughly.

Soundness of cement is one of such vital properties that should be examined properly prior to construction or else the cracks may develop in concrete and its durability will also be reduced. Given below, the details on the soundness of cement.

Soundness of Cement

The properties of hardened concrete or mortar are mainly affected by the different properties of cement. Usually, once the concrete or mortar becomes solidified, they do not set out under expansion or contraction. i.e. the volume of concrete or mortar remains unchanged, as soon as they are set.

Soundness of cement means the strength of cement to maintain its volume as soon as it is solidified. Once the cement mortar or concrete gets dried, there should not be any alteration in volume. If any alteration in the volume occurs, it will allow the cement to inflate or contract. So, the cracks may form. Such cement is known as unsound cement.

If unsound cement is applied in the construction work, the stability of the structures is significantly affected. On the other hand, as soon as sound cement is set, no alternation in volume occurs. Besides, once the sound cement is solidified, no expansion or contraction happens.

Reasons for unsoundness of cement

01. Surplus Lime: With the existence of extra lime (CaO) in the cement, soundness of cement is impacted. This extra lime hydrates gradually and develops slaked lime that absorbs a bigger volume as compared to the original free calcium oxide. Due to the slow hydration process, the properties of hardened concrete are changed.

The variation in the rate of hydration of free lime and slaked lime results in modifying the volume of hardened concrete. The cement that shows this type of volume changes is known as unsound cement. So, a limit is set in the ordinary Portland cement concerning the existence of free lime & magnesia in cement content.

02. Surplus Magnesia: Cement can also be unsound because of the existence of magnesium oxide (MgO), that reacts with water in a manner identical to the lime and influences the rate of hydration.

03. Insufficient Burning: While the manufacturing process of cement is going on, raw materials are supplied into the kiln. Different types of raw materials like lime (Cao) and some acidic oxide get amalgamated inside the kiln. If the burning and cooling processes are not performed in a proper manner, then surplus lime will stay in a free condition. Therefore, it will produce the unsound cement further.

04. Surplus Calcium Sulphate: The expansion is caused by the third compound alias calcium sulphate (CaSo4). Gypsum is included to cement clinker to resist flash setting of cement.

But if excessive gypsum exists it will create reaction with C3A throughout setting and develops calcium sulfoaluminate. This sulfoaluminate creates expansion in hardened concrete. Due to this, the standards limit the amount of gypsum to be included to clinker. The limits are settled in such a manner that the soundness of cement is retained and it does not become unsound.

The soundness of cement should be examined prior to utilize cement in construction. In Indian standards, the soundness of cement is examined through Le Chatelier apparatus test. The manufacturers of cement should also perform the quality control, in order to develop sound cement. If unsound cement is applied for building up your house, the setting time of cement is raised. Under such situation, if formwork is detached before time, the cracks may develop in due course of time. Consequently, the soundness of cement should be examined prior to utilize it in developing concrete.

Properties and benefits of Reactive powder concrete (RPC)

Reactive powder concrete (RPC) stands for the generic name for a class of cementious composite materials which contain superior physical properties, specifically ultra high strength and ductility.

It is formed by mixing fiber reinforced, super plasticized silica fume, cement and quartz sand along with very low water cement ratio. It contains greater compressive strength since quartz sand is applied in place of ordinary aggregate.

Composition of RPC: RPC attains it’s superior properties with a very solid mix containing fine particles and fibers.

1. Low w/cm proportion : 0.16 to 0.24 (as low as 0.13)
2. Type 20M (like type II) Portland cement (no C3A less HoH)
3. Silica fume (25% by weight)
4. Water
5. High dosage of super plasticizer
6. Fine quartz sand (SG = 2.75)
7. Steel fibers (2.5 to 10% by volume) for hardening
8. No rebar necessary


It is cured in steam bath for 48 hours @ 190 degree F (88 degree C) as soon as it is set primarily. It is set under pressure at the molding phase.

Properties of RPC:

Compressive Strength

1. Greater compressive strength as compared to HPC.
2. It is a factor connected with stability of material.
3. Highest compressive strength of RPC is roughly 200 MPa.


Flexural Strength: Plane RPC comprises of extreme flexural strength as compared to HPC (up to 100 mpa). With steel fibers, RPC can attain extreme flexural strength.

Water Absorption: The ratio of water absorption or RPC is very low than HPC. This feature of RPC supports the desired properties of nuclear waste containment materials.

Water penetrability: Water penetrability is reduced in due course of time for all mixtures. 28th day penetrability of RPC is minor than HPC (almost 7 times lower). For water absorption, the application of fibres enhance the penetrability of both types of concrete.

Defiance to chloride ion penetration: It is raised if heat curing is accomplished in concrete. Heat cured RPC demonstrates higher value as compared to normal cured RPC. This characteristic of RPC makes it perfectly fit for being used in nuclear waste containment structures.

Homogeneity: It is enhanced by removing all coarse aggregates. Dry components to be applied in RPC remains under 600 micro meter.

Compactness: Application of pressure prior to and throughout concrete setting period.

Microstructure: Microstructure of the cement hydrate is altered by providing heat treatment throughout curing.

Material Ductility: Material ductility is enhanced through the inclusion of short steel fibres.

Advantages:
1. It has the ability to structurally combat with steel.
2. It has greater stability along with shear capacity that leads to substantial dead load curtailment.
3. RPC is utilized to withstand all but direct primary tensile stress.
4. Superior seismic performance by eliminating inertia load with lighter member.
5. Low and non-interconnected porosity reduces mass transfer, keeping penetration of liquid/gas non-existent.

Some vital points to be considered for RCC false slab prior to casting

RCC false slab stands for a slab that is located under or over the main floor slab.

The false slabs are formed for different purposes. Some false slabs are created for the interior purpose and some other for concealing air conditioning ducts as well as any unnecessary things.

In this article, detail information is given for the false slab that is used in bathrooms for concealing the sanitary pipes, traps, fittings, etc.

The false slabs are formed with several types of materials. But, RCC (reinforced cement concrete) false slab is mostly recognized in bathrooms.

Benefits of RCC false slab:

The sanitary pipes laid on the false slab can be repaired easily.

Due to leakage in the joint of sanitary fittings, the water may fall directly in the bathroom, but false slab can be used to get rid of this issue.

The inhabitants can utilize this for retaining different household things.

Prior to casting the slab, consideration should be given on the following points :-

1. Verify The Clear Distance Among The Floor and The Ceiling of False Slab

Usually, seven feet of distance should be maintained among the bathroom floor and the false ceiling. It is treated as the clear height of the bathroom.

If the clear height is under 7′, lots of issue will be raised. Therefore, it is necessary to retain the false at 7′-2″ over the floor. When the tiles will be set up on the bathroom floor, it’ll be elevated 2″.

Hence, the clear height of bathrooms should be verified properly prior to cast RCC false slab in it.

2. Verify All The False Slab And Lintel Level are Equivalent On a Floor

The level of all lintel and false slab on a floor should remain identical.

For this reason, a level on the floor is settled. Generally, the level is chosen from the front of the lift lobby or stair lobby. Mark the level on a column in the lobby area. Get that level to all flats in that floor.

Prior to cast any false slab, verify the level of the slab relating to the level settled in the column of the lobby area. It should be done prior to cast false slabs to ensure all the lintels and false slabs remain at the similar level on the floor.

3. Verify If The False Slab Is Perfectly Horizontal

The false slab of a bathroom should be perfectly horizontal. Because, if one side of the false slab is raised and another side is down, the problem will arise at the time of wall tiling work of the bathroom.

To make the false slab perfectly horizontal, mark the level in the all four walls of the bathroom by applying a water level pipe. Now verify the spacing among the level mark and the bottom of the false slab in all four sides. If the distances are identical in all sides, then the false slab is perfectly horizontal.
