【摘要】 利用SAP2000实现水平地震作用下筒承式筒仓和地基相互作用的反应分析.引用粘—弹性人工边界,建立各种筒承式筒仓足尺模型,进行基本自振频率计算.分析相互作用对筒仓平动自振基频的影响,为今后进行筒承式筒仓的有限元分析和共同作用下的频率分析奠定了基础.更多还原

【Abstract】 In this paper viscous-spring boundary is introduced.Computer software-SAP2000 for structure is used to analyze the interaction between foundation and silos supported by cylinder.Data files are written according to SAP2000’s special form to establish reinforced concrete silo models.The basic frequency calculation can be done.Then the effect of the interaction between silos and foundation on the basic frequency of vibration can be obtained.Some useful conclusions are drawn through the study.更多还原
