| 摘 要： | 本文运用有限元分析软件对一高层建筑进行结构动力特性分析,建立高层建筑结构的三维计算模型,计算了该建筑物的固有特性;并采用时程分析法进行了地震反应分析,分别计算了四种地震波作用下顶层水平位移的时程曲线、水平位移沿楼高的分布曲线以及顶层加速度的时程曲线。计算结果表明,利用ANSYS软件建立三维模型,能较好的进行结构的抗震分析,并且为抗震设计人员提供可靠的依据。

| Abstract: | The dynamic characteristics analysis of high buildings is discussed by using the large general structural analysis software, by which build 3-D model and obtain the structural characteristics of free-vibration. Moreover, seismic response analysis of a building is carried out adopting time-dependent method. Introducing four natural earthquake waves calculated are the results including time-dependent curve of roof horizontal displacement ,time-dependent curve of roof acceleration, distribution curve of horizontal displacement varying with building height . The results demonstrate that ANSYS can be applied to the seismic response analysis of buildings by 3-D model and the excellent result can be achieved. Therefore, the results can be used for the design of resistant seismic. |
