18. Structure Outline

19. Plan and Side view

20. 3D Model

21. 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 :

22. 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 degrees.
Structure is analyzed for Self weight, Live Load, Wind Laod, Earthquake Load.

23. 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

24. Structural outline with Load

25. 3D Shape with Load

26. 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)

27. 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 : KN / m2

28. 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.

29. 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.

30. 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.

31. 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

32. 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

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

35. Nodal Forces and Seismic Shear Forces At Various Levels Qi = Wi hi2 / Σ ( Wi * hi2 )
Floor Qi Vi 1 2

36. 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.

37. Shear Force and Bending Moment
Maximum Shear Force = KN
Maximum Bending moment = KNm
Maximum Deflection = 24 mm
