Torsion of seismically isolated structures of irregular plan

Abstract

Torsional response of seismically isolated nonsymmetrical multi-storey reinforced-concrete frame structures, subjected to strong seismic action, is considered. Several alternatives of an initially symmetrical structure are analysed (3 levels of torsional stiffness, 3 levels of mass eccentricity), for varied disposition patterns of elastomeric bearings. The results show that regularly arranged seismic isolators can significantly reduce adverse torsional impacts from the superstructure and the isolation system.

Keywords

seismic isolation; nonsymmetrical structure; mass eccentricity; isolation system eccentricity; elastomeric bearing; centre of stiffness
