| 摘 要： | 利用通用有限元程序ANSYS建立了某大型复杂钢结构厂房的三维空间有限元模型，完成了其整体结构的动力学特性分析，还根据现有7级地震记录对其施加了横向、纵向和斜向地震激励，分别做时间历程分析，并对计算结果做了相应的对比．最后结合结构抗震规范的相关条文，对该钢结构厂房的抗震性能进行了综合评定，结果表明其满足7级抗震要求．分析结果可为工程师们设计类似结构提供相应的依据．

| Abstract: | A whole 3D finite element model of a Large Steel Structural Factory Building is established. Then dynamic characteristics and dynamic responses are calculated by importing the seismic excitation in different three directions to evaluate its earthquake resistance. Compared with the Code for Seismic Design of Buildings, the results show that this factory building meets the requests of seismic fortification intensity 7. All the work is helpful for engineers to design similar buildings. |
