【摘要】 张弦梁结构的地震反应是一个非常复杂的过程,抗震问题一直以来困扰着人类,在一次又一次的震害中,地震所造成的伤亡和损失使人们的抗震意识越来越强,固结构的抗震问题已经被提到了一个新的日程。本文重点分析讨论了当改变结构原有的约束形式,及改变索的预张力,结构的地震响应会发生怎样变化。这不仅在理论上丰富了张弦梁结构的地震响应,而且在实践的工程设计中都是有意义有价值的。本文以此为契机,对张弦梁结构的地震反应进行了较深入的研究。现行地震分析方法主要采用振型分解反应谱法。反应谱法理论概念清晰,计算简便易行,为工程设计普遍采用。因此本文在模态分析的基础上,在约束条件及索的预张力改变的情况下对结构进行振型分解反应谱分析。通过ANSYS软件实现张弦梁结构的地震响应分析。更多还原

【Abstract】 The seismic response of beam string structures is a very complicated course,aseismic question puzzleshuman being for a long,in once and once seismic,what seismic take damnify and casualty for human makes human seismic consciousness larger anf larger,so the seismic question of the structures have been refered to a new time. The article emphases analyse and discuss that when restrict form of the structures takes change and traveling-wave effect of cable takes change ,how change the seismic response of structures will take place.It not only abundance theoretically the seismic response of beam string structures,but also it is meaning and value at engineering design at practice.The article chances for it,so the seismic response of beam string structures were researched in depth. The analyse method of the seismic meaning adopt the response spectrum method.The response spectrum method’s concept in focus and account easy,it was adopted by engineering design rifenessly.At the base of mode analyse,the article did the response spectrum method analyse when the restrict form and traveling-wave effect of cable of the structures take place change.By ANSYS,the article implement the seismic response analyse of beam string structures.更多还原
