A portal frame will be used to demonstrate the OpenSees commands. A structural model will be defined first. Subsequently, a number of static and dynamic analyses will be defined and implemented.

The structural model consists of the planar portal frame shown in the figure below: File:GettingStartedGeomtery.JPG


The columns and beam will be modeled as elastic elements. At a more advanced level, these elements can be replaced by more refined element models.

In the analysis phase, the frame will be subjected to three different load cases:

  1. DISPLACEMENT-CONTROLLED LATERAL PUSHOVER;
  2. DISPLACEMENT-CONTROLLED REVERSED CYCLIC LATERAL LOADING;
  3. DYNAMIC GROUND-MOTION-INPUT TRANSIENT ANALYSIS.

In all cases, however, the frame will be subjected to constant static gravity loads:
