Detailed Process for effective slab reinforcement

This construction video will highlight the detailed process for complicated slab reinforcement. All steel bars are connected following the design details. Here the concrete ratio is 1:2:4. This video is very useful for Civil Engineering students as well as various structural engineering professionals.

The slabs containing ratio of longer length to its shorter length (Ly/Lx) larger than 2 is known as one way slab or else as two way slab. In one way slab main reinforcement is equivalent to shorter direction and the reinforcement equivalent to longer direction is defined as distribution steel. In two way slab main reinforcement is rendered alongside both direction.

Detailing Requirements of RCC Slab as per IS456: 2000

a) Nominal Cover:

For Mild exposure – 20 mm

For Moderate exposure – 30 mm

However, if the diameter of bar is less than 12 mm, or cover may be decreased to 5 mm. Therefore for core reinforcement up to 12 mm diameter bar and for mild exposure, the nominal cover will be 15 mm.

b) Minimum reinforcement: The reinforcement in either direction in slab must not be lower than

• 0.15% concerning the total cross sectional area for Fe-250 steel

• 0.12% concerning the total cross-sectional area for Fe-415 & Fe-500 steel.

c) Spacing of bars: The utmost spacing of bars must not surpass

• Main Steel – 3d or 300 mm whichever is lesser.

• Distribution steel –5d or 450 mm whichever is lesser Where, ‘d’ denotes the operative depth of slab. Note: The least clear spacing of bars must not be lower than 75 mm (Preferably 100 mm) even if code does not suggest any value.

d) Maximum diameter of bar: The maximum diameter of bar in slab, must not surpass D/8, where D denotes the total thickness of slab.

Strength of Doubly Reinforced Concrete Beam (compression steel not yielding)

Some useful construction tips to calculate the nominal flexural strength Mn concerning the reinforced concreterectangular section. It is illustrated in figure 9-3(a).

The provided section is reinforced twice with steel in tension and compression zone of the section. The guidelines of ACI-318 is followed for calculating the nominal flexural strength Mn. The highest value of applicable strain at the utmost concrete fiber is supposed to be 0.003.

For fc' grerater than 4000 psi the value of ß1 is calculated as given below;

ß1 = 0.85 - 0.05 {( fc' -4000)/1000} = 0.8

Assume that the compression steel has yielded when the strength is reached (strain in concrete is 0.003).

Given that tension steel consists of 4 bars of #10 (dia 1.27 in.).

Area of one bar of #10 = 1.27 in2.

As = 4-#10 bars. = 4 (1.27) = 5.08 in2.

Area of compression steel , As' = 2-#7 = 2(0.6) = 1.2 in2. The internal forces acting on the section shown in figure 9-3(c) are calculated as given below;

Cc = 0.85 fc' ba = 0.85 (5) (14) a = 59.5 a 

Cs = (fs' - 0.85 fc') As' = (60 - 0.85*5) 1.2 = 66.9 kips

T = As fy = (5.08) (60) = 304.8 kips

Applying static equilibrium, we get Cc + Cs = T;

59.5 a + 66.9 = 304.8

therefore depth of stress block, a = (304.8- 66.9)/59.5 = 3.998 in Depth of neutral axis x = a / ß1 = 3.998/0.8 = 4.997 in

Brief overview of Pin-jointed Truss and different Analysis methods

Truss belongs to a structure that contains straight members to build up one or more triangular units. Generally Pin-joints are used to tie the members of truss at the end. The joints concerning a truss are defined as nodes. External forces and reactions can only function at the nodes and produce forces in the members to be axial forces (tensile or compressive).

If all the members and nodes are positioned inside a two dimensional plane, it is called plane truss. If a truss consists of members and nodes and expands into three dimensions, it is called space truss.

Trusses are inherent parts of various structures like bridges, roof supports, transmission towers, space stations etc.

Truss are defined as:-

a) Statically establish; all the unidentified forces (support reaction and member forces) can be specified with the use of equations of static equilibrium. (provided m+r = 2j).

b) Indeterminate; equations of static equilibrium can’t solely find out unknown forces, provided m+r> 2j.

c) Unstable; not appropriate to bear load; provided m+r < 2j; Where ‘m’ denotes member’s no in a truss; ‘r’ denotes number of reaction components; And ‘j’ denotes number of joints in a truss;

Analysis methods:

Two methods are available for determining the forces in the members concerning a truss;

(i) Methods of Joints : This method focuses on the equilibrium of the all joints concerning the truss. There exists two equations of static equilibrium ?Fx & ?Fy.So one has to start with the joint containing lower than 2 unknown forces. Go through problem 3-1 (civilengineer.webinfolist.com)

(ii) This method is useful while finding out the forces in a few members. Under this method, a fictitious is passed over the members in which forced should be set and to obtain unidentified forces, select the equilibrium of the left hand side or the right hand side of the truss.Go through problem 3-2 (civilengineer.webinfolist.com)

How to design, model and analysis of Space Truss with SAP2000-19

This is an exclusive presentation for Civil Engineering students. By going through this construction video, one can learn how to create the design, modeling and analysis of Space Truss alias Triangular Arch Truss through SAP2000-19, an exclusive integrated, productive and practical structural program.

As defined by architecture and structural engineering field, a space frame or space structure refers to a truss-like, lightweight rigid structure built up with interwoven struts in a geometric shape. Space frames are applied to range vast areas by means of few interior supports.

Similar to truss, a space frame is endurable due to the constitutional hardness of the triangle. Adjustable loads (bending moments) are delivered as tension and compression loads along the length of each strut.

In a space truss or space frame structure, there exists a three-dimensional truss to combat with lateral forces. In a normal truss, horizontal, vertical, and diagonal members function on a single plane whereas a space truss applies diagonal connections which seperate outside of the plane.


A space truss generally appears as various interlocking pyramidal outlines. A tetrahedron shape belongs to the elementary space truss, containing six members which converge at four joints.

Bubble deck slab system can reduce your building cost significantly

Bubble deck slab belongs to the kind of slab where bubbles or ellipsoid, formed with waste plastic material, are used to replace some portion of the concrete to lessen the self-weight of the structure.

This type of slab is designed by following the Euro and the British codes. In 1990, JORGEN BREUNING had developed a new system where ellipsoids are locked amid the top and bottom reinforcementmeshes and a natural cell structure is formed similar to a solid slab.

The slab is made having the same features of a solid slab, but contains significantly less weight because of the reduction of unnecessary concrete.

Bubble deck slab system was first introduced in The Millennium Tower in Holland.

Advantages of Bubble Deck Slab System:

• Preserves 30 to 50 % weight than a equivalent solid slab – equal stiffness.

• 20% concrete lessening in other components.

• The decreased weight of the slab will lead to a modification in design to longer spans and/or condensed deck thickness.

• It can be easily used with seismic as it minimizes the total weight of the building.

• Minimize concrete usage – 1 kg recycled plastic substitutes 100 kg of concrete.

• With this system the cost of the building is decreased by 8 to 10 %.

An effective road paving method to construction a long-lasting road or walkway

This construction video focuses on some exclusive process for efficient road paving. Road pavement belongs to the long lasting surface material set on an area projected for defending sustain vehicular or foot traffic, like road or walkway.

Now-a-days asphalt or concrete become very popular to set on a compacted base course. Permeable paving methods are also undertaken in recent times toward low-impact roadways and walkways.

There are various types of road pavements which range from Asphalt, Concrete, Composite Pavement, Recycling, Bituminous surface, Gravel Surface, Other Surfaces like Brick, cobblestone, sett, wood plank, and wood block.

Asphalt pavement is most popular all through the globe. Under this method a paving team is formed. The trucker driver is considered as the first person in the paving team who fulfils the asphalt into the paver's hopper.

Two individual conveyors together transmit the material via the machine to the backside, where it is allocated consistently amid paver and screed through two separately controlled rotating screw conveyors. While paving a standard mix, the temperature must be over 110 °C to arrange adequate time for compaction.
