| 摘 要： | 由于索膜结构的变形具有明显的非线性,使得传统的谱分析计算会带来的较大的误差,利用ANSYS有限元程序,对封闭式组合膜结构进行了自振特性计算,并输E l Centro水平波进行了动力时程分析。结果表明,对于索膜结构,时程分析方比谱分析法更为可靠;索膜结构耦合现象明显,结构响应复杂,地震下的位移变化显著;所讨论的封闭式组合膜结构工程中,中部和两侧膜面区域的地震反应较大,起封闭作用的膜面在地震作用下性能良好。

| Abstract: | The traditional spectrum analysis will cause visible errors because of the obvious nonlinear characterristic of cable-membrane structure.The vibration properties of the closed combined membrane structure and the dynamic time history analysis of the structure under El Centro wave are performed by the ANSYS program.Some conclusions are obtained that the response of the structure by time history analysis is more reliable and larger than by spectrum analysis,the coupling of the structural parts is obvious,the response of the structure is complex and the varieties of displacements are significant.The central and side membrane areas'response are large,but the whole closed membrane possesses good properties. |
