Structural Design Using STAAD PRO

Use of Computer in Structural Designing of Buildings

In earl ier periods say in sixties, engineering calculations were done by

slide rules. Then in seventies, came the era of calculators, which

replaced slide rules completely. The calculators are very much in

vogue these days but to aid the structural engineer have come

computers which are high-speed calculators and much more. When

similar members (say, slabs, beams columns, footings) are to be

designed, relevant computer programs can be used to get more accurate

methods which were earl ier difficult and time -consuming to use

manually. For example, frames under horizontal loads were analysed by

portal or cantilever methods manually. These gave only approximate

results and we had to be satisfied with them. But now, computer can be

used effectively to get accurate results.

Computer-Aided Analysis & Design :-

Computers have recently been brought in to aid structural designers.

These machines are as effective as the available software (i.e.

computer programs). Programs are available for design of slabs, simply

supported and continuous beams. Columns under biaxial bending ,

isolated footings, combined footings and rafts. There are also available

2-D plane frame programs, grids, retaining walls, etc. not only all the

available programs may be to the liking of a designer. The assumptions

made in the development of some programs may not be acceptable to

the structural designer and in one case, it was found that the column

program purchased was valid only for short columns and not for long

columns, although at the time of purchase, it was claimed to be valid

for both short and ling columns.

In practice, continuous beams, frame analysis under horizontal loads

are almost always solved by a computer. Sometimes, an building is

divided into frames in both the principal directions. All the frames

with the vertical and the horizontal loads are put in the computer a nd

the solution is got which includes the complete design of beams at all

the floor levels. Column loads are then assembled manually. Column

design under biaxial bending at all levels is done by a computer

program.

A very powerful program STAAD Pro is also available in the market

which can be used for 3-D analysis of a building as a whole. It is

useful for analysis and design of multi -storied buildings. We may

DESIGN

Once analysis is completed for different load combination design will be perform for load envelope case.

Concrete Design can be done either using IS456 or for ductile detailing IS-13920 can also be used.

Using STAAD Pro for analysis & design the Building as a whole

Steps in design

1. Manual design of slabs, stairs, chajjas, non -grid beams, etc.

2. Preparing data for STAA PRO program at all levels i.e

generation of model, load intensities at al l floors and wall load

as u.d.l, support conditions, material properties etc

3. Using computer, feeding data and gett ing the out -put. It gives

beam and column design at all levels and it also gives column

loads for design of foundations..

4. Manual design of footings.


Page:12


5. Preparation of structural drawings with foundations and upwards

by AUTOCAD or by manual.

After analysis and design by STAAD Pro software we have to note

down area of steel for column at various levels & grouping is done

accordingly.

For beams be have to do detailing as per SP-34 by noting down the

main reinforcement & Shear reinforcement & at various section floor

wise.

The drawings are prepared floor -wise, starting from the foundation,

plinth beam and upwards and issued to the site for execution in the

same order.
