V. IS 875 (Pt 3) 2015 WL Generation on Rectangular Clad Bldg

Determine the lateral wind loads on a three-story clad building per the IS 875 (Part 3): 2015 code.

Details

  • Building length along wind when wind blow +X or -X direction, Lx = 9 m
  • Building length across wind when wind blow +X or -X direction, Lz = 12 m
  • Building length along wind when wind blow +Z or -Z direction, Lz = 12 m
  • Building length across wind when wind blow +Z or -Z direction, Lx = 9 m
  • Building Height, h = 9 m
  • Basic Wind Speed, Vb = 47 m/s (Location Agra as per ANNEX A of IS 875 3:2015)
  • Terrain Category: Terrain Category 1 (Cl 6.3.2.1 as per IS 875 3:2015)
  • Risk Coefficient Factors, k1 = 1.0 (All general buildings from Table 1 of IS 875 3:2015 )
  • Topography Factor, k3 = 1.0 (Up wind slope (ϴ) below 3 degree from Cl 6.3.3.1 of IS 875 3:2015)
  • Importance Factor for Cyclonic Region, k4 = 1.0 (All other Structures from Cl 6.3.4 of IS 875 3:2015)
  • Wind Directionality Factor for Buildings, Kd = 0.9 (From Cl 7.2.1 of IS 875 3:2015)
  • Area Averaging Factor, Ka = 0.9 (From Table 4 of IS 875 3:2015)
  • Combination Factor, Kc = 0.9 (From Cl 7.3.3.13 of IS 875 3:2015)

Validation

Calculate the design wind speed and pressure:

There is no variation in either for the first 10 m in height, thus the values are constant for the height of the building.

  • Terrain & height factor, k2 (from Table 2 of IS 875 (Part 3): 2015) = 1.05

The design wind speed:

Vz = Vb × k1 × k2 × k3 × k4 = 47 (1.0) (1.05) (1.0) (1.0) = 49.35 (Cl 6.3)

Wind pressure at height, z = 10 m:

Pz = 0.6 × Vz2 = 0.6 (49.35)2 = 1.461 kN/m2 (Cl. 7.2)

Design wind pressure:

Pd = Kd × Ka × Kc × Pz = (0.9) (0.9) (0.9) (1.461) = 1.065 kN/m2 (Cl 7.2)

Check the minimum wind pressure: 0.7 × Pz = 1.023 < Pd, OK.

Internal pressure coefficient:

  • Cpi = 0.2 (Positive internal Coefficient as the building opening not more than 5 % From Cl 7. 3.2.1 of IS 875 3:2015)
  • Cpi = -0.2 (Negative internal Coefficient as the building opening not more than 5 % From Cl 7. 3.2.1 of IS 875 3:2015)

External Pressure Coefficient when wind Positive (+X) Direction (From Table 5 of IS 875 3:2015):

  • External Pressure Coefficient wind along +X on face A, Cpe = 0.7
  • External Pressure Coefficient wind along +X on face B, Cpe = -0.25
  • External Pressure Coefficient wind along +X on face C, Cpe = -0.6
  • External Pressure Coefficient wind along +X on face D, Cpe = -0.6

equiv joint load = influence area × avg. intensity of wind pressure × net pressure coefficient
