Structural Design Using STAAD PRO
Use of Computer in Structural Designing of Buildings
In earlier 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 earlier 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 and
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

consider the followings methods of approach in order to tap the full
capacity of STAAD Pro software.

Analysis is performed to predict the response of a structure to
applied external loads.
Real world structural problems are very complex in nature.
Analysis of these problems requires idealization.

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 all floors and wall load
as u.d.l, support conditions, material properties etc
3. Using computer, feeding data and getting 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.

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.
