Example 6.1 Nonlinear Static Analysis of the Shear Wall Structure
with Input Force
Consider a shear wall structure as shown in Figure 6.8(a) with
l
w
= 6 m and
h
w
= 4 m. The sec-
tional parameters are shown in Figure 6.8(b) and the numerical parameters are provided in
Table 6.1. Let us attempt to solve the response of the shear wall structure subjected to the lateral
force
F
= 5 MN in the FAM.
