Shear walls A2-A7 and I2-I7
1 kip = 4.448 KN
1 kipft = 1.356 KNm
1 foot = 0.305m
Vwall = 37.9 kips (169 KN)
M = Vl = (37.9)(10' = 379kft (514 KNm)
)
Shear strength of wall = (84 x 12")(8")(174) = 1403 k (6241 KN) > 37.9 k (169 KN), OK
Check need for boundary zones;
M/Vl = 379/37.9(84) =.12 < 3.0 (No boundary zones required)
Shear wall lines (C7-C8 and G7-G8)
Shear wall lines C & G resist shear forces from the upper roof and the sacristies.
Vupper = 6.86k (30.5 KN)
Vsacristy = 1.97k (8.76 KN)
Torsion:
From sacristy in longitudinal direction = 0.673 k (2.99 KN)
From sacristy in transverse direction x 30% = 0.3(0.3kip) = 0.09kip (400N)
Total torsion (for orthogonal effects = 0.673 + 0.09 = 0.763k (3.39 KN)
Total shear = 6.86 k + 1.97k + 0.76k = 9.6 k (42.7 KN)
