Response of simple slip-type systems to transient excitations

Abstract

The response of single-degree-of-freedom elastoplastic systems of the "slip type" is investigated for various ground motions, and the results compared with those obtained for linear systems and for conventional elastoplastic systems. Some attention is also given to the response of bilinear elastic systems having the same resistance-deformation relationship as the skeleton curve of the resistance diagram for the elastoplastic systems. The input motions considered include a half-cycle velocity pulse, a half-cycle displacement pulse, and an earthquake motion. The response quantity investigated is the deformation of the spring, particularly its absolute maximum value.
