Example 4. Model & Analysis Combinations and Results

The following combinations of model-building and analysis can be performed with this example. The results for each set of input files is shown below the commands. For static analysis, base shear is plotted versus relative lateral displacement of top node with respect to base support. For the dynamic analysis, the relative lateral displacement is plotted versus time step. The relative displacement is taken as the different between DFree.out and DBase.out. For the uniform-support excitations, DBase is zero, as the supports experience accelerations without displacements (it's all relative deformations of the structure). For the multi-support excitation, the non-zero DBase records the support displacements, which are the input.

The sine-wave excitations for both uniform and multiple-support excitations were set to be the same in this example. Comparison of the plots shows that the relative displacements of the two cases are the same.... as expected.
