Structure Seismic Response Analysis under Pile-Soil-Structure Interaction

Article Preview

Abstract:

This paper makes a numerical simulation for a high-rise frame building with the basement by using the structural analysis program SAP2000. The seismic response of the building under interaction of pile-soil-structure (SSPI) is analyzed. A parametric study that involves evaluating the linear elastic seismic performance of eleven, thirteen and fifteen story buildings with one underground story, and buildings having one, two, three and four underground stories, and the influence of different soil stiffness was performed. It is found that the SSPI can greatly affect the seismic response of buildings in terms of the dynamic characteristics and deformation behavior. It is found that, for some of the cases considered, SSPI effects increase both the vibration period and horizontal displacement of the buildings. And some rules on seismic performance of buildings with the influence of parameter variation are summarized.
