Analyzed as a Space Frame Structure using STAAD – III
package.
Total No. of Joints : 388
Total No. of Members/elements
: 548
Total No. of Supports
: 56
Total No. of Degrees of Freedom
: 1992

Modeling
•Ring Beam in the Structure is modeled
as a set of straight line elements.
•Ring Beam is broken into straight beam
at an interval of 5.625 degrees.
•Structure is analyzed for Self weight,
Live Load, Wind Laod, Earthquake
Load.


Assumed Loading as per
IS Codes
Unit Weight of Concrete : 25 KN / m3
Unit Weight of 200 thick solid Concrete Block
Wall
: 24 KN / m3
Floor Finish
: 1.0 KN / m2
Live Load at Type Floor : 3.5 KN / m2
Live Load at Roof Level : 1.5 KN / m2


Structural outline with Load


3D Shape with Load


Wind Load Analysis
Design Wind Speed = Vb * k1 * k2 * k3
where Vb = Basic Wind Speed in m / s.
k1 = Risk Coefficient = .91
k2 = THS Factor =1.02
k3 = Topography Factor = 1
Vb = 44 m / s for Hyderabad
Terrain Category : 2(Open terrain with scattered
obstructions of height between 1.5m to 10m)
Class of Building : B(Structures having max.
dimensions between 20m to 40m)

Wind Intensities
Design Wind Pressure = 0.6 Vz2
All Data is from IS – 875 ( Part – 3 ) – 1987
Exposure Factor At all Joints : 1
At 1st Floor :
1.0008 KN / m2


Wind Load Analysis
The wind load on a building shall be calculated for the
building as a whole.
Wind Load on the Building = Cf * Ae * Pd
where Cf = Force Coefficient
Ae = Effective Frontal Area
Pd = Design Wind Pressure
The value of Cf is 0.5 from Table – 23 of IS : 875 ( Part – 3 )
for buildings of circular shape.
Wind Load at each floor is distributed among the columns at
that floor accordingly their relative stiffness.


Earthquake Design Consideration
•The Building will be designed for
horizontal seismic force only.
•The Structure is analyzed as an
equivalent static approach employing
the use of a Seismic Coefficient
Method.


Terminology
•Basic Seismic Coefficient ( α0 )
To give the basic design acceleration as a fraction
of the acceleration due to gravity.
•Importance Factor ( I )
To modify the basic seismic coefficient and seismic
zone factor, depending upon the importance of structure
•Soil Foundation System Factor ( β )
To modify the α0 and seismic zone factor,
depending upon soil foundation system.
•Design Horizontal Seismic Coefficient ( αh )
Seismic coefficient taken for Design.


Earthquake Load Consideration
•Earthquake Zone ( Hyderabad )
•Basic Horizontal Seismic
Coefficient ( α0 )

: II
: 0.01

•Coefficient depends upon soil
foundation system ( β )( Hard Soil ) : 1.0
•Importance Factor ( I )
: 1.5
•Design Value of Horizontal Seismic Coefficient,
αh = β * I * α0 = 0.015


Base Shear Calculation
The Base Shear is given by,
Vb = K * C * αh * W
Where K = Performance Factor according to
structural framing system =
1
C = Coefficient defining the flexibility
of structure depends upon the
no.
of storeys in structure = 0.75
αh = Design Seismic Coefficient
W = Total DL + 25 % of LL

Base Shear Calculation and It’s
Distribution among Floors
•Base Shear,
Vb = K * C * αh * W
= 1 * 0.62 * 0.04 *1947.2
= 482.9152 KN
•The distribution of forces along with the
height of the building is given by,
Qi = Vb * ( Wi * hi2 ) / Σ ( Wi * hi2 )


Nodal Forces and Seismic Shear Forces At
Various Levels
Qi = Wi hi2 / Σ ( Wi * hi2 )
Floor

Possible Load Combinations
•( Dead Load + Live Load ) * FoS
•( Dead Load + Live Load + Wind Load ) *
FoS
•( Dead Load + Live Load + Earthquake
Load ) * FoS
•For 1st case FoS will be 1.5 and for the rest
of the case FoS will be 1.2 as per IS – 456.


Shear Force and Bending Moment

Maximum Shear Force = 930.20 KN
Maximum Bending moment = 2079.17 KNm
Maximum Deflection = 24 mm
