| 摘 要： | 通过对钢框架、钢支撑钢框架和钢骨消能支撑钢框架结构体系的弹性反应谱分析、弹性以及弹塑性时程分析,对比研究了3种钢框架结构体系的抗震性能。分析结果表明,钢骨消能支撑钢框架结构体系能有效地消散输入结构的地震能量,减少结构地震反应对钢框架梁柱的非线性性能的需求。同时由于钢骨消能支撑的作用,避免了钢框架结构的局部失稳,提高了结构的弹塑性变形能力和延性。

| Abstract: | Through elastic response spectrum analysis as well as elastic-plastic time-history analysis by inputting a strong ground motion record,story drift and displacement are compared among different steel frame structures using BRBs, a frame using conventional braces and a non-braces frame.The comparisons show that the story drift and displacement of the frame using BRBs are smaller that those of the other two frames.Conclusions are drawn that the use of BRBs can enhance the structure's ductility,dissipate the energy effectively,and reduce the nonlinear demand of the columns and girders. |
