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:
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:
- DISPLACEMENT-CONTROLLED LATERAL PUSHOVER;
- DISPLACEMENT-CONTROLLED REVERSED CYCLIC LATERAL LOADING;
- DYNAMIC GROUND-MOTION-INPUT TRANSIENT ANALYSIS.
In all cases, however, the frame will be subjected to constant static gravity loads:
