Strong Motion Drift Estimates for R/C Structures

Abstract

A simple procedure is described by which to obtain estimates of maximum inelastic response displacements for a certain class of reinforced concrete building structures subjected to strong ground motions. The procedure is based on elastic response spectrum analysis techniques. Change in vibration period and energy dissipation attributable to inelastic response are taken into account. The procedure is tested by comparing maximum computed displacements with those measured in numerous tests of small‐scale structures. Results of the comparison indicate that the procedure produces good results for a variety of structural systems and over a wide range of response.
