Pier Size Is 1.5 x 1.5 Mtr.

Sol:-

Mumbai Wind = 44 m/s

As per IS875 Part-3 (Appendix A)

Vz= Vb*K1*K2*K3*K4

K1 = Probability Factor

K2 = Height Factor

K3 = Topography Factor

K4 = Importance Factor

Screen Shot is K1,K2,K3,K4 Table

Vz= 44*1.07*1*1*1.3 = 60.632

Wind Pressure is = 0.6*Vz

= 0.6*60.632= 36.3792
