LUMDYNF Computer Program

1.3.0 Seismic Load

Seismic Load is analyzed by another in-house computer-aid program named LUMDYNF. LUMDYNF is a structural dynamic computer-aid program by using modal analysis method; and, seismic load is applied by response spectrum.

An example of a three-story building as shown in Figure 3.1 is performed for seismic analysis. The column stiffnesses and generalized masses are also shown in Figure 3.1. The height of each story is assumed to be 10 ft., 10 ft. and 15 ft., accordingly. The accelerating response spectrum is shown in Figure 3.2.
