Earthquake response of asymmetric structure considering soil-structure interaction in time domain

摘要

A study is carried out on lateral-torsional coupling response considering soil-structure interaction in time domain.Acoording to lateral-torsional coupling vibration equations of soil-asymmetric structure system,the direct integral MATLAB program in time domain were made used method.The parametric research on elastic dynamic response of soil-asymmetric interaction system in time domain was done by directed integral program.By comparing the parameter influence rule in time domain with the result in frequency domain,it verified the feasibility of using time history method to do parametric research.This conclusion can supply references to study the laws how the parameters influence the inelastic seismic response.
