| Abstract: | In order to study the feasibility of the forced decoupling method in solving the earthquake response of soil-asymmetric structure interaction system,the time domain analysis is made here on lateral-torsional coupling response.Acoording to the lateral-torsional coupling vibration equations of soil-asymmetric structure system,the direct integral MATLAB program in time domain is made by using Wilson-θ method,and the feasibility of the forced decoupling method is verified by comparing the result in time domain with the result in frequency domain.Finally,it is derived that the results are very close to each other,which could verify the feasibility of the forced decoupling method.This conclusion could supply references to the engineering calculation and structural design of similar projects. |
