【摘要】 本文采用有限元法对烟台火车站拱式马鞍形屋盖进行了地震时程响应分析。计算模型采用空间杆系结构,与站房一起建立整体模型;选用美国的Elcentrol波、中国天津(1976)地震记录和一组人工加速度时程曲线;利用ansys软件进行模态分析及抗震计算。通过分析,得到了一些指导性结论,可供结构设计参考。更多还原

【Abstract】 According to the theory of finite element,based on the structural analysis program-ANSYS ,3D-glob- al model of steel roof and buildings of Yantai Railway Station is introduced in detail.The roof of station is saddle in shape and arch in structural style.Using this model,the vibrational frequency and mode are calculated,and seismic time-history response analysis is studied under Elcentrol,Tinjin and an artificial groun motion.Some conclusions are obtained and can be referred for design of this kind of structure.更多还原
