Influence of Three Hysteretic Models on the Inelastic Displacement Response Spectra of Confined Masonry Walls Under Seismic Loading


Abstract eng:
In this article, the influence of three hysteretic models on the inelastic displacement response spectra of a confined masonry wall under seismic loading is evaluated. This study is done using ten strong-motion accelerograms taken from the SAC Phase 2 Steel Project that were recorded at Los Angeles area. For this purpose, the three types of behavior in hysteretic characteristics are: 1). Elasto-plastic model without degradation of strength and stiffness; 2). Hysteretic model with cyclic degradation of strength and stiffness; 3). Hysteretic model with cyclic degradation of strength and stiffness that takes into account the pinching phenomenon. In all cases, the differential equation of motion is solved by the Adams-BashforthMoulton method. From this study, it can be drawn some conclusions about the degree of refining the hysteretic model and its influence on the maximum inelastic displacement response spectra of a confined masonry panel. Results indicated that the degree of refining is not significant.
