Combined Pad Foundation Design Spreadsheets

Combined Pad Foundation Design Spreadsheets comprise of a series of spreadsheets which can be used for stability analysis and structural design of a combined rectangular pad foundation.

The spreadsheets evaluate the loadings input by the user and work out the best possible pad size to transmit these loads into an tolerable bearing pressure into the soil.

Unique Pad Sizing and Eccentricity Charts simplify the process for the designer to opt for the best pad dimensions.

As soon as the pad size is set, the spreadsheets then workout the design bending moments and the necessary reinforcement in both X and Y directions for sagging and hogging. The designer can then indicate the perfect reinforcement arrangement with unique recommended reinforcement chart which demonstrates graphically the existing reinforcement arrangements to fulfil both necessary cross sectional area and spacing requirements.

Then a summary page is formed and a reinforcement drawing is produced to provide the perfect reinforcement arrangements which the user has indicated.

The suite comprises of a total of 4 spreadsheets :

• A simple combined pad design spreadsheet to make analysis of a simple combined pad foundation depending on two axial loads where the consequential load must operate through the centroid of the base.

This spreadsheet is ideal for most cases and facilitates making design rapidly for straight forward situations.

• A complex integrated pad design spreadsheet that can easily analyze any combined rectangular pad foundation on the basis of axial, horizontal or moment loadings.

These spreadsheets contain all the tools to design complicated issues or where close attention should be given to detail. It can deal with any size rectangular pad and rectangular columns to where space is restricted in one direction. The spreadsheet also arranges the base for being loaded eccentrically in any arrangement required by the designer.

It comprises sliding analysis to rationalize any horizontal loads. It involves design charts to make brief analysis of shear and punching shear loads, and comprises of bending moment and shear force diagrams to facilitate the designer to design the reinforcement in as much detail.

Both simple and complex spreadsheets are available to abide by either British Standards BS8110 & BS8004 or Eurocodes BS En 1992 & BS En 1997.

What should be the qualities for becoming a successful civil engineer

In order to become a successful civil engineer, the following qualities are essential :-

1. TESTS OF BUILDING MATERIALS: An efficient civil engineer should be well versed with various test methods of building materials. Given below, the details of some crucial test methods :-

Concrete Test: Slump test, compression test, split tensile test, soundness etc.
Soil Test: Core cutter test, compaction test, sand replacement test, tri axial test, consolidation test etc.
Bitumen Test: Ductility test, softening point test, gravity test, penetration test etc.

2. EXAMINATION OF SOIL: Prior to build up a construction, different types of soil tests are accomplished to define the settlement and constancy of soils. Therefore, as a civil engineer, one should possess adequate knowledge with these tests to carry on at the job site.

3. APPLICAIONS OF SURVEYING INSTRUMENTS: Each civil engineer should have clear conception on how to apply various surveying instruments like the total station, theodolite etc. These instruments are specifically designed for marking and measurements.

4. STANDARD CODES USED IN CONSTRUCTION: Each country should contain their standard safety specifications (eg: Is Code) for construction associated works. The construction works of new buildings should abide by the rules and processes indicated in the standard codes. if not, there are chances for collapsing of the structure any time.

5. BAR BENDING SCHEDULE: Bar bending schedule is a vital chart for civil engineers. It offers the reinforcement calculation of RC beam like cutting length, type of bending, the length of bending etc.

6. DRAWING AND DESIGN: Drawing and design are considered as the elementary part of a running project. It offers all the necessary specifications of that project. Each site engineers should possess the quality for evaluating such drawings and designs.

7. COMPUTATION AND BILLS: A civil engineer should have the skills to produce the estimation and bills in a construction project.

8. QUALITY CONTROL: With proper quality control, the profit of the project is raised and the cost is decreased. Therefore, a engineer should be well versed with quality control process.

9. ON SITE MANAGEMENT: A engineer should have adequate knowledge with form-work, concreting, safety measures etc.

Various types of Design Loads on Bridges, Highway & Rail Bridge

While going to deign any bridge, the tasks like computation of Design Loads and loading bridge model are very important. Given below, some crucial loads which should be taken into consideration at the time of creating the design of a bridge.

Dead Load - “Gravity loading because of structural parts of bridge”

Dead load comprises of permanent gravity forces because of structural Elements. It is basically measured as the product of volume and material density. Normally, self-weight is employed in the analysis model with the self-weight option of the analysis software. This makes the calculation step simple.

Superimposed Dead Load - “Dead Gravity loading because of non-structural parts of bridge”

Superimposed dead loads stand for gravity loads that include other permanent items ranging from parapets and road surfacing and other non-structural and architectural attachments to the bridge. Such items last long but should have been modified during the lifetime of the structure. It has similarity with self-weight and it is measured as the product of volume and material density.

The most crucial item of superimposed dead load belongs to the road pavement or surfacing. It is not atypical for road pavements to become gradually thicker over a number of years since every new surfacing is just placed on top of the one before it. Therefore, specifically high load factor is employed to road pavement.

Imposed traffic Loading - “Because of road or rail vehicles”

Imposed traffic loads contain those forces which are produced with road or rail vehicles on the bridge. Bridge traffic can be vehicular, rail or pedestrian/cycle or genuinely any combination of these. The type and strength of the design vehicle alters on the basis of the design code. As for instance, HL-93 is used in AASHTO design code.

Bridge traffic loading is frequently monitored by trucks whose weights significantly surpass the maximum legal. Bridge traffic loading is used with the notional lanes which do not depend on the actual lanes. Eurocode normal loading comprises of invariable loading and a pair of four wheels in a single lane.

To examine the dynamic effects of traffic, the vehicular loads are multiplied with an impact factor frequently.

Pedestrian and cycle track - “Gravity loading because of non-vehicular traffic”

Bridge codes normally indicate a basic intensity for pedestrian loading. Again intensity is based on the design code, it is 5 kN/m2 in the Eurocode and the British standard and 4 kN/m2 in the American code.

How to design any one way simply supported slab

In this construction video tutorial, you will learn how to create the design of one way slab (simply supported slab) that is standing on the masonry wall.

You will also gather information on all checks for making design of the slab.

The requirements and materials of the slab are given below :-

Clear span = 3m
Live load = 4000 N/m2
M20 concrete and fe 415 steel are used here.

The calculation is made on the following dimensions :-

A bearing of 120 mm is provided at each end. The distance among centers of bearing = 3+0.12 = 3.12 m

Necessary effective depth = Span/20 x modification factor
= 3120/20 x 1.40 = 112 mm

The bars with 8 mm diameter are arranged with clear cover of 15 mm.
Effective cover = 15 + 4 = 19 mm

Overall necessary depth = 112 + 19 = 131 mm

It is necessary to arrange an overall depth of 135 mm

So, effective depth = 135-19 = 116 mm

The Dead load of the slab will be calculated as follow :-
25 x 135 = 3375 N/m2 (floor finished with C20 mm).

Live load = 4000 N/m2
Therefore, total load = 7855 N/m2
Factor load = Wµ = 1.50 x 7855 = 11782.5 N/m2

Designs with raised Foundations in the flood likely area

Building plans are most important for creating a worth dream house that will be flood resistant and beautiful, but also have open spaces and areas for everyone.

Construction Industry is a difficult and risky area to perform the jobs on time, as while making buildings the contractors or builders have to face various kinds of problems like weather problem, natural disaster and the problem created by men or law etc. It becomes more difficult when any area deals with various kind of natural disaster such as flood or earthquake related areas where the buildings have to be more stable.

Architects and designers are continuously trying to find a kind of structure for home that will be firm enough to handle every kind of natural calamity. Here are some examples of the building designs that are made for the flood related area:

Easy does it

The Chatham Home Planning, Inc. has made a design of a simple and open costal cottage that has outdoor living options on the two levels including a veranda, deck downstairs and a private balcony for the upstair master suit; besides that there are private bathrooms, dual walk-in closets and two lavish bedrooms. The other level also has walk-in closets as downstairs and on the main floor there is a big kitchen nearby the open dining room with a beautiful fireplace in the living room. In addition of the two bedrooms, there are two more bedrooms sharing a hall bath attached with laundry.

The Suite Life

Visbeen Architects has designed a unique drawing where every bedroom is a suite in a breezy gateway and the main level has a large open dining room with a large table and entrances a deck on the one side. The big suite lodges on the same level and also has two decks and one of them is private; the upper one has a big space for family and friends get together. There is a sitting area on the landing that offers the great view which is the peace of mind.

Elevated Living

The design of Donald A. Gardner, Inc. provides an elevator in the house providing more comfortable to the people, the elevator starts with the storage level and goes all the way up to the top level where the two bedrooms give with a beautiful view. The main gathering space has a latest open layout with a seamless flow outside the balcony. The placement of the cooktop on the island makes it easier to talk with everyone while cooking, while the master suite includes a private balcony and a super-handy connection to the laundry room.

Relaxing on the Porch

A simple home design with separate bedroom layout that keeps all the living spaces on an equal level and has an elevator to go everywhere. The kitchen space has seating area for three people with close presence to the big room and open dining area; people can have their work in the studio or can step out to the back porch stretching straight from the beautiful master bedroom.

More about design drawings and model planning

Planning: Building plans can be somehow difficult to get as the planning for every kind of building is not same and they upgrades and changes every day.

Plans are like a set of drawings or two-dimensional diagrams that are used to narrate a place or object or to communicate building or fabrication instructions which are drawn or printed on paper and can take the form of a digital file.

Planning are generally made for different technical purposes like architecture, engineering or construction etc. and those capture all the geometric features of a site, building, product or component in an accurate and clear way so that it can display a clear information to the builder or manufacturer to help in design.

Generally this process of making plans and producing them is known as technical drawing and a working drawing is a kind of technical drawing where documentation has to be done to build any engineering product or architecture such as civil, architectural, structural, mechanical, electrical and plumbing etc. In the same way there is some software that helps to plan the models for building purpose or designing in other way such as BIM describes the process of creating and managing digital information about a building or other facility like bridge, highway, tunnel etc. and many more. BIM ensures that actual information should be created in a right format at the appropriate time so that better decisions can be taken in throughout the design, construction and operation of built assets.

At the beginning of a project, the BIM is known as Project Information model might include previous information like site reviews, condition reviews, information about previous services and many more and all those information should be generated from a previous Asset Information Model or Aim to operate and maintain a built asset.

A design intent model is developed in the time of design stages going in a project and it gets more detailed with the growth of the project and at last it will become a Virtual Construction Model with all other objects in the model to be manufactures, installed or constructed.

Design Drawings: they are used to develop and communicate ideas about a developing design and in the beginning stage of designing them only demonstrate to the client the capacity of a particular design team to grasp the design.

These designs are used in developing and communicating the detail, examine potential sites and assess options and develop the approved idea into a consistent and co-ordinate design and communicate the developed design to the local planning authority, contractors and suppliers.

Besides that it also keeps the track of the completed construction and constant changes in completing the construction project. But it is also true that some of these are not always known as design drawings as sometimes they has not started well or completed early. But all of them have some things of investigation or development of the design or sometimes they are good for nothing.

So these design drawings can be categorized as:

• Feasibility studies.
• Option appraisals.
• Concept drawings.
• Detailed or developed design.
• Technical design.
• Tender drawings.
• Shop, installation and construction drawings.

Design drawings are developed in a detailed way from block and massing drawings, sketches to detailed technical drawings etc. but while developing it are important to know the purpose and about the information the designs can narrate through them. They must determine their actual format, size, scale and every little detail that will be useful for the drawings suppliers to use in fabrication. These drawings can be prepared by architects, technicians, structural engineers, civil engineers and so on other different practitioners; but they must be carefully integrated and co-ordinated to give security about the right level of design in all the elements. These drawings has been revolutionized at first by CAD and then by BIM.
