Pushover analysis of 3-dimensional frame structures for performance based designs can be done for reinforced concrete, structural steel and steel-concrete composite sections.
Hinge connections are essential to pushover analysis in order to simulate displacement. Various hinge types for trusses, beams, columns, walls, and springs. Multi-linear hinges and user-defined hinges can be defined as well.
Hinge displacement control and force control features enable you to model force and displacement incrementally. This makes it possible to calculate the reactions of the structure over the course of several sequential steps. This capability is essential in pushover analysis since displacement due to seismic loading occurs incrementally and must be modeled as such in order to create an accurate simulation.
The program also checks for key design criteria such as drift limits, deformation, and strength capacity. This function saves you the time and effort of having to check these design limits yourself.
