The Analysis of Seismic Response for Base-Isolated Structure by LS-DYNA
Abstract eng: LS-DYNA, a popular large-scale explicit finite element analysis software, adopt viscous boundary to simulate the effects of infinite field. It can solve the problems of SSI more effectively and conveniently. But because the precision of the viscous boundary is not high enough, viscous-spring boundary is introduced to substitute for viscous boundary. As demonstrated by numerical calculation results, this approach can improve the calculating precision obviously. A 7-storied base-isolated frame structure is analyzed with improved LS-DYNA in this paper, and essential models are established to compare the seismic responses of fixed base and base-isolated structures under 8 degree frequently and 8 degree rarely seism with SSI.
