Models for Inelastic Response of Beam-Plate Assemblages

A simplified method to account for inelastic behavior in beam-plate assemblages is proposed. This numerical technique, which is easier to implement, eliminates the need for iterative steps required in similar methods based on flow rule. In addition, two models for determining the progression of inelastic zones in beam and plate type elements are presented. Based on this procedure and models, the nonlinear response of some typical structures subjected to static and dynamic loads are determined. Comparison of the obtained solutions with results, both theoretical and experimental, reported by other investigators demonstrates the validity of the techniques utilized.
