钢结构半刚性连接节点研究现状

Research Status of Semi-Rigid Connection Nodes in Steel Structures

半刚性连接具刚度、延性和载荷能力,抗震性能优越,施工难度低,是实用且经济的连接方式。但半刚性连接受力复杂,力学特性分析难度大,且国内规范中缺乏针对性的分类标准和设计方法。综合国内外文献规范,简述了梁柱节点的分类及特点,详细介绍了钢结构半刚性节点连接类型、研究方法和研究成果,通过分析当前研究进展,指出未来所需研究的问题与方向,为钢结构半刚性节点研究、设计与实际运用提供思路与参考。

Semi-rigid connection with stiffness,ductility and load capacity,excellent seismic performance,low construction difficulty,is a practical and economic connection.However,the force of semi-rigid connection is complicated,and it’s difficult to analyze the mechanical characteristics.There is a lack of specific classification standards and design methods in domestic norms.Based on domestic and foreign literature norms,the classification and characteristics of beam-column joints are briefly described,and the types,research methods and research results of semi-rigid joints of steel structures are introduced in detail.By analyzing the current research progress,the problems and directions for future research are pointed out,providing ideas and references for the research,design and practical application of semi-rigid joints of steel structures.
