Wind loads in the N-S direction
The equivalent wind loads at each floor level are calculated as follows:
Alternate (1) Slab and column framing
Interior frame (24 ft bay width)
Roof = 22.4
6.0
24/1000
= 3.2 kips
4th = 21.8
12
24/1000
= 6.3 kips
3rd = 21.0
12
24/1000
= 6.1 kips
2nd = 20.1
12
24/1000
= 5.8 kips
1st = 18.8
13.5
24/1000
= 6.1 kips
Alternate (2) Structural walls
Total for entire building (121 ft width)
Roof = 22.4
6.0
121/1000
= 16.2 kips
4th = 21.8
12
121/1000
= 31.6 kips
3rd = 21.0
12
121/1000
= 30.6 kips
2nd = 20.1
12
121/1000
= 29.2 kips
1st = 18.8
13.5
121/1000
= 30.7 kips

Wind loads in the E -W direction
Using the same procedure as for the N-S direction, the following wind loads are obtained for the E-W direction:
Alternate (1) Slab and column framing
Interior frame (24 ft bay width)
Roof = 2.3 kips
4th
= 4.4 kips
3rd
= 4.2 kips
2nd
= 4.0 kips
1st
= 4.1 kips
Alternate (2) Structural walls
Total for entire building (61 ft width)
Roof = 6.9 kips
4th
= 13.4 kips
3rd
= 12.9 kips
2nd
= 12.2 kips
1st
= 12.6 kips
