Document Type: Journal Paper


Two different models of nonlinear beams which can be used to represent the girders and columns of a nonlinear multistory structure are described and compared. One beam model is limited to bilinear bending moment-end rotation hysteretic characteristics. The other model can have different curvilinear and bilinear hysteretic characteristics at each end. Three different definitions of ductility factor are made and applied to yielding beams. These types of beam models can be used in studies of the dynamic response of earthquake excited multi-degree of freedom yielding structures.
