In-Depth Information
The second example in 3D shown in Figure 4.34 is of a plane triangular grid, rigidly
supported along one side and subjected to a point transverse load at its apex (node 7). All
members have the same stiffness and plastic moment. The output shown in Figure 4.35
indicates failure occurs when the transverse load approaches a value of 1.55.
