ABSTRACT
High-rise structures need much time for its time consuming and cumbersome calculations using conventional
manual methods. STAAD-Pro provides us a fast, efficient, easy to use and accurate platform for analyzing and
designing structures. The principle objective of this project is to analysis and design a multi-storied building
G+19 (3 dimensional frame) using STAAD Pro software. The design involves analyzing the whole structure by
STAAD Pro. The design methods used in STAAD-Pro analysis are Limit State Design conforming to Indian
Standard Code of Practice. We conclude that STAAD-PRO is a very powerful tool which can save much time
and is very accurate in designs. In this project, G+19 storied building is considered and applied various loads
like wind laod, static laod ,earthquake load and results are studied and compared by manual calculations.
Keywords: high rise building, seismic load, STAAD pro
I. INTRODUCTION
Nowadays, Construction of high rise
building is a basic need because of scarcity of land.
Conventional method of manual design of high rise
building is time consuming as well as possibility of
human errors. So it is necessary to use some
computer based software which gives more accurate
results and reduce the time. STAAD-PRO is the
structural software is nowadays accepted by
structural engineers which can solve typical problem
like static analysis, wind analysis, seismic analysis
using various load combination to confirms various
codes such as IS 456:2000, 1893:2002, IS 875:1987
etc.
II. OBJECTIVE
Following specific objectives has been made for the
present study-
 To develop, design and analysis model of the
High rise structure in STAAD-Pro.
 Study of seismic and wind load applied to the
structure as per IS 875 and IS 1893.
 Comparison of results of earthquake load
applied on the structure by STAAD-Pro and
manual calculations both by seismic coefficient
method.
 To verify deflection obtained by STAAD-Pro
with IS codal Limit..
III. METHODOLOGY
A Model of G+19 storeyed is developed,
analysis and design using STAAD-Pro software.
Building plan size is 33.6m × 18.8m. The building is
situated in Pune in earthquake zone ǀǀǀ. eismic zone
coefficient is taken as 0.06 as per IS code. Following
specifications are given to the structure:
Column 0.30 m × 0.60 m
Beam 0.45 m × 0.45 m
Slabs 0.15m thick
Parapet Wall 0.1 m
Live load 2kN/m2
Floor Finish 1kN/m2
Grade of concrete M30
Grade of steel Fe 415
These values are provided as a input to the staadpro
software for drawing, analysis and designing
purposes.
Supports: The base supports of the structure is
assigned as fixed..
Loading:
The loadings were calculated partially manually and
rest was generated using STAAD.Pro load generator.
The loading cases were categorized as :-
 Dead load
 Live load
 Wind load
 Seismic load
Self-weight
The self weight of the structure can be
generated by STAAD.Pro itself with the self weight
command in the load case column.
RESEARCH ARTICLE OPEN ACCESS

Dead Load From Slab:
Dead load from slab can also be generated
by STAAD.Pro by specifying the floor thickness and
the load on the floor per sq m.
Calculation of the load per sq m was done
considering the weight of beam, weight of column,
weight of RCC slab, weight of terracing, external
walls, internal walls and parapet over roof.
External Wall Load = 13.8 kN/m2
Internal Wall Load = 4.6 kN/m2
Seismic load:
The seismic load values were calculated as
per IS 1893-2002. STAAD.Pro has a seismic load
generator in accordance with the IS code mentioned.

IV. RESULTS
Graph shows the maximum deflection
occurs when the earthquake load in x-direction
acting on the structure. As height increases,
deflection is also increases. Hence graph of height
v/s deflection varies linearly.
Graph 1. Height V/S Deflection due to EQ Force in
X direction
Graph shows the maximum force occurs
when the earthquake load in x-direction acting on
the structure. Effect of the earthquake load in z-
direction is approximately same. As height
increases, magnitude of force is also increases
Graph 2. Height v/s Earthquake Force in
X direction
Graph shows the maximum force occurs
when the earthquake load in x-direction acting on
the structure. Effect of the earthquake load in z-
direction is approximately same. As height
increases, magnitude of force is also increases.
It gives the details for beam such Grade of
concrete, steel, sectional dimensions, cover and
section-wise top and bottom reinforcement details
for flexural and shear requirement. similarly for
column, it provide interaction ratio as per Clause
39.6, IS 456:2000
It also provide the data for concrete take off for
beam, column and slab.
Steel bar daimeter and according the weigth
requiremnet is provided by Staad pro.
 We have compared results of base shear
obtained by Staad pro with Manual calculations.
Values obtained by Staad pro is greater than
manual calculations by approximately 5%.
 Total volume of concrete required =2385.1
cu.meter
 Total steel required =2820.65KN
V. CONCLUSION
STAAD PRO is a versatile software has the
capability to calculate the reinforcement needed for
any concrete section, to find lateral deflection due to
earthquake load . The program contains a number of
parameters which are designed as per IS: 456(2000)
, IS 1893:2002. Various structural action is consider
on members such as axial, flexure, torsion etc
according to their response.
Design of beam for Flexure:
STAAD Pro gives SFD and BMD for
individual member and whole structure. It suggests

the adequacy of the section as a singly reinforced
section, doubly reinforced section.
Beam Design Output:
The default design output of the beam
contains flexural and shear reinforcement provided
along the length of the beam.
Column Design:
Columns are designed for axial forces,
uniaxial and biaxial moments at the ends. Square
columns are designed with reinforcement distributed
on each side equally for the sections under biaxial
moments and with reinforcement distributed equally
in two faces for sections under uni-axial moment.
All major criteria for selecting longitudinal and
transverse reinforcement as stipulated by IS: 456
have been taken care of in the column design.
Base shear :
Base shear plays an important role. Its
gives the base shear for entire structures.
Storey drift:
High rise structures are subjected to
excessive deflection. Deflection obtained by
STAAD pro is checked by IS Codal limitation for
serviceability.
