摘要
运用振型分解反应谱法分析超高层钢结构的地震响应时有若干影响因素,包括计算模型的选择,合理振型数目的确定,遇合法则的选用等.针对武汉国际证券大厦这类空间作用明显的超高层钢结构建筑,运用大型有限元软件ANSYS建模分析计算,讨论以上影响因素对于计算结果的影响,对运用有限元软件对大型复杂结构的反应谱抗震分析有借鉴价值.
There are several influence factors in response spectrum analysis of super high-rise steel structure, including the selection of calculation model, the consideration of number of reasonable vibration mode and the choice of combination method. Wuhan International Security Mansion super high-rise building is calculated by finite element analysis software ANSYS. The influence factors to the calculation result above are discussed. The study can be served as the references of spectrum analysis of such super high-rise structure using finite element software.
