  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 : 179280

  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 5.625 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

  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 : 1.0008 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 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 )

  34. Nodal Forces and Seismic Shear Forces At Various LevelsQi = Wi hi2/ Σ ( Wi * hi2 )

  35. 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.

  36. Shear Force and Bending Moment Maximum Shear Force = 930.20 KN Maximum Bending moment = 2079.17 KNm Maximum Deflection = 24 mm
