| 摘 要： | 以3个巨型钢框架结构为例,假设4个计算方案,输入代表不同场地条件的5条典型地震波,应用有限元分析方法,对不同计算方案的算例进行三维弹性地震时程反应分析。通过对不同计算方案结果的比较分析,研究考虑楼板刚度与否和次框架对巨型钢框架结构反应的影响,为进一步深入研究巨型钢结构的抗震性能及抗震设计提供基础。

| Abstract: | Three mega steel-frame structures are selected as examples,four analytical models are hypothesized,and five typical earthquake waves are selected,which represent different site conditions respectively.Using finite element analysis method,three-dimensional elastic history time analysis of three mega steel-frame structures with different analytical models subjected to different earthquake ground motions is conducted.In order to study influence on response of mega steel-frame structures from floor stiffness and hypo-frame,the results of different examples are compared.The conclusions obtained lay foundation for studying the seismic performance and seismic design of mega structures profoundly. |
