| 摘 要： | 为明确某复杂钢框架结构的受力性能,文中采用YJK和MIDAS两种软件对该结构进行分析对比,采用弹性时程分析法对该结构进行多遇地震下补充分析,应用YJK软件对结构进行静力弹塑性分析,对蒙皮结构进行考虑材料非线性和几何非线性的全过程分析,考察了楼板小震和中震作用下的应力分布规律,结果表明,结构各项指标均满足相应规范要求,可见该结构具有良好的抗震性能,为同类工程设计提供参考。

| Abstract: | The software of YJK and MIDAS are used to analyze and compare the mechanical behavior of a complex steel frame structure.The time-history analysis method is used to supplement the analysis of the structure under frequent earthquakes.YJK software is used to carry out static elastic-plastic analysis of the structure under rare earthquake.The whole process analysis of the skin steel structure considering material nonlinearity and geometric nonlinearity is carried out.Slab stress under frequent earthquake and fortification earthquake is also analyzed.The results,provide a reference for the structural design of similar projects,show that all the indices of the structure meet the requirements of the relevant code and the structure has good seismic performance. |
