Cyclic pushover analysis may be performed using either of two approaches, outlined as follows:

Sequence of nonlinear-static load cases

Cyclic pushover analysis may be performed through a sequence of chained pushover analyses. Two key aspects of this approach include:

Time-history load cases

An alternate approach is to use a single nonlinear time-history load case.

Some special considerations are necessary when using a time-history load case to model applied loading, listed as follows:

 

A sample of a time function is shown in Figure 1:
