| 摘 要： | 在带悬臂梁段拼接的刚性钢框架中,如果将梁的高强螺栓拼接节点设计得弱一些,可以利用其摩擦消耗地震能量文中首先根据已有的节点试验研究,提出该类拼接节点2种典型的滞回模型,并通过对试验构件滞回性能的数值模拟,验证所提出模型的有效性将该模型用于模拟框架结构中的拼接节点,利用SAP2000对框架结构进行弹塑性时程分析,研究耗能拼接节点对框架结构整体抗震性能的影响研究结果表明,利用拼接耗能的钢框架可以提高结构的耗能能力,从而改善结构的抗震性能

| Abstract: | If the high-strength bolted splice joints with cantilever beam in rigid steel frame is designed weaker,it can be used to absorb earthquake energy by friction.According to the experimental study of splice joints,two typical hysteretic models are shown in the paper.Hysteretic behavior of splicing member is simulated to verify the effectiveness of the model.Splice joints in frame are simulated by the model,and elastoplastic time-history analysis of steel frame with SAP2000 is used to study the influence of ene... |
