Performance‐based testing specifications for seismic isolators

Abstract This paper presents a study that determines the conditions of testing for determining bounding properties seismic isolators use in analysis and design test is meant to be replacement tests Items 2(a) 3 ASCE/SEI‐7. Then separately, adequacy maximum considered earthquake Item 4 The are determined by performing analyses with models account time‐variant computing resultant isolator displacements. In work, large number isolation systems (total 96 systems, single friction pendulum, triple pendulum lead‐rubber), three different hazards as measured spectral acceleration at period one second, collection bi‐directional ground motions short‐ long‐duration characteristics (71 pairs each duration, hazards) were considered. Fundamental this methodology which (friction or characteristic strength) dependent on instantaneous temperature sliding interfaces lead core.
