4. In order to compete in the ever growing
competent market it is very important for a
structural engineer to save time.
As a sequel to this an attempt is made to
analyze and design a Multistoried building by using
a software package Staad pro.
For analyzing a multi storied building one has to
consider all the possible loadings such as dead,
live, wind and seismic loads.
ABSTRACT
6. INTRODUCTION
Buildings are the important indicator of
social progress of the country.
Daily new techniques are being developed.
A building frame consists of number of bays
and stories.
7. This project is mainly based on software
and it is essential to know the details about
these software
Staad pro(v8i)
SOFTWARES
8. Staad is the powerful design software licensed by Bentley .
Staad stands for structural analysis and design
staad pro is a very powerful tool which it does this job in just an
hours staad is a best alternative for high rise buildings.
Now a days most of the high rise buildings are designed by
staad which makes a compulsion for a civil engineer to know
about this software
STAAD PRO
9. CODES
IS-456:2000:DESIGN CODE FOR RCC
STRUCTURES
SP-16 : DESIGN CODE FOR COLUMNS
IS-875(PART 1) : FOR DEAD LOADS
IS-875(PART 2) : FOR IMPOSED LOADS
IS-875(PART 3) : FOR WIND LOADS
10. 1.Utility of building :Residential building
2.No of storeys : G+4
3.No.of staircases : 5 no's
4.Type of construction :
R.C.C frame structure
5.Type of walls :Brick wall
STATEMENT OF THE PROJECT
11. Concrete Grade : M20, M15
All steel grade : Fe450 grade
Type of steel bars : HYSD
MATERIAL DETAILS
12. DIFFERENT TYPES OF LOADS
ON THE STRUCTURES
Dead loads
Live loads
Wind loads
13. RCC slab
Beams
Columns
Walls
DEAD LOADS
INVOLVES SELF WEIGHT OF
14. Live load also known imposed loads
Loads over the floor i.e. Load of persons it
is calculated as 1 KN/m2
This load is applied over the length of
structure
LIVE LOADS
15. Wind is air in motion
Intensity of wind and exposure are applied in the direction as
required
The amount of wind load is dependent on the following:
Geographical location,
The height of structure,
Type of surrounding physical environment,
The shape of structure,
Size of the building.
WIND LOADS
16. The notation adopted through out the work is same
as in IS 456-2000
Using partial safety factors for loads in accordance
with clause 36.4 of IS 456-2000
Partial safety factor for material in accordance with
clause 36.4.2 IS456-2000 is taken as 1.5 for
concrete and 1.15 for steel
Using partial safety factors in accordance with
clause 36.4 of IS 456-2000 combination of load
(D.L+L.L) 1.5
(D.L +L.L+W.L) 1.2
ASSUMPTION AND NOTATIONS ASSUMED
17. MATERIAL DENSITY
1.Plain concrete 24.0 kN /m3
2.Reinforced 25.0 kN /m3
3.Flooring material(c.m) 20.0kN/m3
4.Brick masonry 19.0kN/m3
LIVE LOADS: In accordance with IS 875 part-2
1.Live load on slab = 3 kN/m3
2.Live load on passage = 3 kN/m3
3.Live load on stair = 3 kN/m3
DENSITY OF MATERIALS USED
