Abstract:

Frame-shear wall buildings with multiple basements are the most commonly used structural form of high-rise buildings in the world today. In the traditional design method, structures are usually assumed as rigid base structures without considering soil-structure interaction (SSI), since incorporating the dynamic SSI tends to prolong natural periods and increase the damping of the system, which are considered beneficial for the seismic response of structures. However, recent studies exposed a potentially harmful aspect of SSI. In this study, a soil-foundation-structure model developed in finite element software and verified by shaking table tests is used to critically investigate the influence of SSI on high-rise frame-shear wall structures with a series of superstructure and substructure parameters. The beneficial and detrimental impacts of SSI are identified and discussed. Numerical simulation results indicate the rise in the stiffness of subsoil can dramatically amplify the base shear of structures. As the foundation rotation increases, inter-storey drifts are increased and base shears are reduced. In general, SSI amplifies the inter-storey drifts showing detrimental effects of SSI. However, as for the base shear, SSI exerts detrimental effects on most piled foundation cases as well as classical compensated foundation structures founded on Ce soil, whereas, for classical compensated foundation structures founded on soil types De and Ee, effects of SSI are beneficial since the base shear is reduced. Moreover, regarding structures with different foundation types, minimum base shear ratios considering the SSI reduction effect are presented.
