VERIFICATION AND VALIDATION OF MODELS OF ELASTOMERIC SEISMIC ISOLATION BEARINGS

摘要

User elements are developed for analysis of elastomeric seismic isolation bearings in OpenSees. These elements implement advanced numerical models of low damping rubber, lead-rubber, and high-damping rubber bearings, which can be used to analyze base-isolated nuclear structures subjected to extreme ground shaking. The formulation and implementation of the elements in OpenSees are discussed. The verification and validation of the user elements, which followed ASME best practices, are presented.
