Calculate the second column of the lateral stiffness matrix (Ri2, 02 = 1) for the confined masonry cantilever wall shown. The footing, width = 1 m and length = 3 m, rests on a flexible soil with a subgrade coefficient equal to 10,000 ton/m2 x m. Suppose:

Confinement columns:

Ec = 2,000,000 ton/m2

thickness = 0.15 m

Masonry wall:

Ea = 500,000 tons/m2

Ea/Ga = 2.5

thickness = 0.15m
