[摘要] 以烟台龙口南山集团会展中心X区的辐射式张弦梁结构为背景，利用有限元软件SAP2000，对结构进行了时程分析。分析结果表明在三种地震波的激励下结构的时程曲线性质基本相同，在激励时间内表现稳定，结构的抗震性能良好。

Abstract: Time history analysis of a radiant string beam in Nanshan Expo Center area X at Longkou, Yantai is studied using FE software SAP2000. The numerical results indicate that the properties of time-dependant curves are basically the same and steady under the excitation ofthree simulated seismic waves. The radiant beam string structure has well seismic behaviors.
Keywords: radiant beam string structure; time history analysis; time-dependant curve; dynamic performance
