Nonlinear System Analysis / Dynamics

Capacity curve in spectral representation
Capacity curve in spectral representation

The new pushover analysis is a nonlinear method for the verrification of earthquake safety of structures and can be used alternatively to the response spectra method.

Here, the displacement of a control node is compared with the total earthquake force (capacity curve), which occurs under constant vertical loads and monotonically increasing horizontal loads.

The method is suitable for largely regular structures whose basic eigenmode in the direction considered is not determined by torsional vibrations
