| 摘 要： | 新型抗震隅撑支撑框架(knee-braced frame,KBF)是在梁柱连接的附近设一起耗能作用的隅撑,主支撑连接在此隅撑上构成的抗震结构体系。与偏心支撑体系EBF抗震结构体系对比,具有大震时框架结构不易损坏、维修方便的优点。采用有限元考察了不同的隅撑形式、不同高宽比下KBF结构的性能。在分析总结的基础上,系统地提出了KBF框架的抗震设计要求和有关的计算公式。

| Abstract: | A new earthquake-resistant system(knee-braced frame,KBF) was investigated,in which an energy dissipation knee brace near the beam-column joint,and the main brace is connected to the knee brace.Compared with EBF,the beams and columns in KBF will sustain limited plastic deformation in strong earthquake,and repair work in KBF after earthquake is very convenient.The elastic and elastic-plastic behavior of the KBF is parametrically investigated.Based on those researches,design requirements and corresponding form... |
