| 摘 要： | 为深入探讨高层建筑的动力响应问题,以15层高楼为例,运用大型有限元分析软件ANSYS,分析了高层建筑结构的动力特性,建立三维空间板梁结构有限元模型,计算了结构的固有频率和固有振型.用时程分析的方法研究了常遇烈度、设防烈度和罕遇烈度地震载荷作用下顶层的最大位移响应,三种烈度的最大位移分别为6.080 6、21.010 3和29.041 5 mm.结果表明:地震烈度越大,结构的动力响应越大.三种烈度下的结构最大层向变位角均出现在第三层,说明第三层为整个结构的薄弱层,为工程抗震设计提供了参考依据.

| Abstract: | The dynamic feature of high buildings is discussed in the present study with the application of ANSYS, the large finite element analysis software, aimed at the analysis of dynamic response of high buildings. Based on the case of a 15-story-building, a model of beam and shell 3-D finite element structure is built and the frequency of structure and the mode of vibration are computed in the study ; furthermore, the structural dynamic response is discussed under different seismic waves with the use of the history analysis method. The results show that the more intense the seismic wave is, the bigger is the dynamic response of the buildings. The information can be used for the anti-seismic design of structure. |
