【摘要】 预应力预制框架(简称为PTED框架)结构的受力性能取决于梁柱连接截面处的受力性能。为了研究梁柱连接处关键设计参数对节点受力性能的影响,基于弹塑性有限元分析程序OpenSees,提出PTED节点的数值模拟方法,对关键设计参数进行参数化分析,并在参数分析的基础上,给出一些相关的设计建议,从而为确定PTED框架结构的设计方法奠定理论基础。更多还原

【Abstract】 The mechanical performance of the prestressed frame( referred to as PTED frame) structure depends on the mechanical performance of the cross section of the beam-column connection. To study the impact of the key design parameters on the beam-column joints,the numerical simulation of the PTED joints was proposed based on the elastoplastic finite element analysis program Open Sees. The key design parameters were analyzed,and based on the analysis of the basic parameters,some related design proposals were given. The theoretical foundation for the design method of the PTED frame structure was built.更多还原
