The analysis of the response of building structures to dynamic loads is a difficult task, especially if the response is nonlinear, as in the case of concrete buildings subjected to strong seismic ground shaking. This is one of the most difficult tasks facing the structural engineer. The methods available for linear elastic analysis are summarized briefly, together with comments on the development of proper mathematical models for such analysis. A discussion of the main techniques suitable for the inelastic analysis of concrete buildings follows, again accompanied by practical guidelines for mathematical modeling for such analyses. The last section provides a list of several computer programs for engineers contemplating inelastic analyses of concrete buildings.
