M/Vl = 128 / (7.9)(18) = 0.9 < 3.0 (no boundary zones required in upper wall portion)
Mbase = (7.9)(26.25) + (21.91+0.81+1)(10' = 445 kft (603 KNm)

Shear wall line 7 (Walls 7A-7C & 7G-7I same by symmetry)
Shear wall line 7 resists shear forces from the upper roof, lower sloped areas and the sacristies.
Vupper = 3.015k (13.41 KN)
Vlow sloped roof = 5.79k (25.75 KN)
Vsacristy = .99k (4.40 KN)
Torsion:
From lower sloped roofs in transverse direction = 11.8 k
From sacristy diaphragm in transverse direction = 0.68 k
From lower sloped roof in longitudinal direction x 30% 3.2(0.30) = 0.96 k
From sacristy in longitudinal direction x 30% = 1.53(0.30) = 0.46k
Total torsion (for orthogonal effects = 13.9k (61.8 KN)
Total shear = 3.02 k + 5.79k + 0.99k + 13.9k = 23.7 k (105 KN)
