半刚性节点研究综述及展望

随着钢框架体系的广泛应用,其理论设计体系的研究更显突出,其中梁柱连接节点的半刚性连接是最重要的部分。《钢结构设计规范》(GB50017-2003)中对半刚性连接提出了条文要求,但没有必要的理论支持。目前,关于半刚性节点的理论研究落后于工程实践,急待形成设计的理论体系,特别是需要建立弯矩和转角的本构方程用于工程设计。结合国内其他单位的研究成果,把本课题组从2000年至今5年来对半刚性理论与试验的研究进行总结分析,以推动实用理论的发展。

SUMMARY AND PROSPECTS OF SEMI-RIGID JOINT

With widespread application of steel frame system in our country, the study on theoretic design system appears more outstanding.The semi-rigid joint of beam-to-colum connections is the most important and critical part.The articles are raised about semi-rigid joint in "Code for Design of Steel Structures" (GB50017-2003) promulgated recently.But it has no necessary theoretical help.The theoretic study falls behind engineering practice.There is an urgent need to form the theoretic design system.Specially the equation about moment and angle should be built for engineering design. It has been summarized and analysed theoretic and test studies on semi-rigid joint that our task group have been doing since 2000, combining other organizations' study results. Whose purpose is to do some work for perfecting practical theory used for engineering design.
