Random Vibration Study of Structures under Multi- Component Seismic Excitations

摘要

A random vibration study of structures under multi-component seismic excitations is presented in this paper. The pseudo excitation method proposed by J.H. Lin is employed and is further developed, from which a multi-component pseudo Excitation method is formulated. then, the random model and correlation for multiple Ground motions are investigated. Based on the method, a computer program is Developed and a random vibration study is performed for a double-layer spherical Lattice shell to investigate its seismic performance under multi-component seismic Excitations.
