Abstract
Much of the work conducted in the past to predict building damage during
earthquakes, had relied on the consideration of simple inelastic one-degree-of-
freedom systems to predict the nonlinear response of actual structures. A number
of different nonlinear formulations for complete plane frames have been
available since the 1960's, but, unfortunately, they have not been thoroughly
validated comparing their predictions with experimental data. In this paper,
several nonlinear analysis models for frames are reviewed. Two computer
programs for nonlinear dynamic analysis of plane frames, DRAIN-2DX and
IDARC2D, are used to predict the response of a frame building. Their
predictions are compared among themselves, to those of a fiber model
implemented by the authors,
