Abstract
In this paper,the author combinated the powerful function of Ansys with the equivalent incentive,constructed the multi-dimension ground motion equivalent excitation loads of the structure,on the base of both translational and rotational acceleration excitation of the seismic surface ground motion.The structure was analyzed on the momentum by using the finite element program of Ansys.and at the same time,the characteristic of random response of the structure was found,as the result of the application of the equivalent excitation method.Finally.the goal of doing random vibration analysis of architectural structure under multi-dimensional ground motion excitation was realized.关键词
