dc.description.abstractAn analysis of a one-storey model of a torsionally coupled base isolated building for two-component random ground motion is presented. The base isolator consists of an array of elastomeric bearings between the base of the building and its foundation. The hysteretic behaviour of individual bearings is assumed to be elastoplastic. The response analysis considers the effect of the interaction between the restoring forces in the two principal directions on the yielding of the individual bearings. The response of the system is obtained under different parametric variations in order to investigate the effectiveness of base isolation and the effect of force interaction during yielding of the bearings on the response. The effectiveness of base isolation is quantified with the help of the response ratio between the mean peak responses of the torsionally coupled system with and without base isolation. It was observed that the biaxial force-interaction during the yielding of the bearings has considerable influence on the response.en
