- Abstract
- The report presents an evaluation of the effect of inelastic deformation on the preliminary analysis and design of earthquake resistant structures. The first part of the study deals with the interaction between ground motion and structural response parameters. The purpose is to provide a more consistent basis for selecting the design earthquake for systems that response inelastically. Major emphasis is placed on assessing ways to define the damaging potential of a ground motion. The second part of the study involves developing an efficient analysis procedure for use in the preliminary stage of design. Response of typical shear-beam type structures in their initial linear elastic mode shape coordinate systems is presented. In the last part of the study, a preliminary investigation of the seismic behavior of non-structural subsystems supported on inelastic structures is performed. The effects of the severity of inelastic deformations, of different hysteretic characteristics of the structure and of the amount of viscous damping of the subsystem are investigated.
