| 摘 要： | 用SAP2000结构分析软件建立了具有4种防压曲支撑布置方式的7层钢框架平面模型，进行了模态分析、时程分析与推覆分析，对比分析了不同支撑布置方式下结构的内力、变形、支撑内力及内力重分布规律。分析表明，支撑布置方式对防压曲支撑钢框架抗震性能有一定影响。在此基础上，探讨了防压曲支撑布置方式的影响规律，特别是对内力重分布及破坏机制的影响，并据此提出了建议。

| Abstract: | Four structural plane models of 7-storey steel frame with different layout of anti-buckling braces were set up using SAP2000 structural analysis software, the model analysis, time history analysis and pushover analysis were conducted, and the structure internal force, deformation, support internal force and internal force redistribution rule in different support layout modes were compared and ana- lyzed. The analysis showed that the support layout modes had certain effect on seis- mic performance of anti-bulcking steel frames. On ing law of the layout modes on seismic performance the basis of analysis, the influency on redistribution of internal force and damage mechanism were discussed and suggestion was put forward. |
