Elastic-Plastic Time-History Analysis for Super Tall Building-Foundation-Soil Interaction under Earthquake
In order to study the seismic response of super tall building, super tall building-foundation-soil interaction (SFSI) was considered under earthquake excitation in time domain. Meanwhile the program of force restoring constitutive models of concrete, steel bars, steel frame structure was developed. In addition, the nonlinear characteristic of soil was presented by Cohr-Moulomb criterion which matches Drucker-Prager criterion. The model of 3-D elastic-plastic seismic response of SFSI was established. The viscous damping of soil and the nonlinear contact between soil and foundation were considered. By taking practical engineering example of super tall building, the dynamic behaviors and elastic-plastic time-history analysis were calculated. The results of analysis showed that the dynamic behaviors and mechanics of structural components obviously changed. The results have significant engineering application for the seismic time-history analysis of SFSI.
