To calculate wind load for industrial steel structures and to apply it by using TSD

1. Generate manual wind loading in the design report based IS code as per the following input

• Basic wind speed = 39m/s
• Terrain category 2

BASIC WIND SPEED=Vb= 39 M/S

Vz = Vb *k1*k2*k3*k4

ki= probbility fctor = 0.92

k2= terrain roughness and heigt factor =1.06 (building height 18 m)

k3= topography factor = 1.0

k4= importance factor = 1.15

Vz = 39*0.92*1.06*1.0*1.15

= 43.73 m/s

design wind pressure Pz = 0.6*Vz*Vz

= 0.6*43.73*43.73 =1147.38 n/m2 =1.147 kn/m2

Pd = Pz*Kd*Ka*Kc , and value should not be lesss than 0.7 Pz

Pd= 1.147 kn/m2

h/w =0.9

l/w=1

ANOTHER PROJECT

Pd = 1.147 kn/m2

h/w = 10/40 =0.25

l/w =60/40 = 1.5

roof angle =23

3. On a separate model generate wind loading using wind wizard
