Structure Outline


Plan and Side view


3D Model


Details of The Model

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

Original Bandwidth : 358

Reduce Bandwidth : 16

Size of Stiffness Matrix : 179280


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 AnalysisDesign 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 AnalysisThe 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 ) : II

•Basic Horizontal Seismic

Coefficient ( α0 ) : 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 * hi

2 )


Nodal Forces and Seismic Shear Forces At Various Levels

Qi = Wi hi2 / Σ ( Wi * hi

2 )

Floor Qi Vi

1 391.7677 482.9151

2 91.1473 91.1473


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
