4.10 Two-bay wall

Back

The two-bay wall in Fig. 4.37, which carries a constant edge load of 50 kN/m

on the upper edge, was analyzed with bilinear elements (Q4), Wilson’s element

(Q4 + 2), and boundary elements. As expected (see Table 4.6), the support

reactions of the three solutions are nearly identical, but also the stresses in

section A − A do not deviate very much; see Fig. 4.38. This is a bit of a

surprise, considering the seemingly large distance between the load case ph

(Q4) and the original load case p; see Figure 4.37 a and b.
