我国装配式钢框架结构梁柱连接节点研究现状

Research Status of Beam-Column Connection Joints of Assembled Steel Frame Structure in China

在装配式钢框架结构中,梁柱连接节点是重要的设计内容,其构造合理性对整体结构的安全性和经济性有重要影响.为了进一步研究梁柱连接节点相关技术,推动装配式钢结构建筑发展,本文总结和梳理了近年来我国装配式钢框架结构梁柱连接节点的研究现状.根据柱截面形式的不同,分为H型钢柱-钢梁连接节点和钢管柱-钢梁连接节点,对各种类型连接节点的构造及其工作特性进行了总结分析,探讨了装配式钢框架结构梁柱连接节点存在的问题及发展方向.

In the fabricated steel frame structure,beam-column connection joint is an important design content,and its structural rationality has an important impact on the safety and economy of the overall structure.In order to further study the related technologies of beam-column connection joints and promote the development of assembled steel structures,this paper summarizes and sorts out the research status of assembled steel frame beam-column connection joints in China in recent years.According to the different section forms of columns,it is divided into Hsection steel column-steel beam connection joints and steel pipe column-steel beam connection joints.The construction and working characteristics of all types of connection joints are summarized and analyzed,and the existing problems and development direction of beam-column connection joints of assembled steel frame structure are discussed.
