钢框架梁柱节点转角对钢框架的内力和变形及其梁柱构件的设计有着重要的影响。通过试验测量或计算机模拟所得的节点弯矩-转角(M-)曲线是分析节点性能对钢框架受力性能影响的最为重要的依据之一。研究了节点各个组件的受力状态和变形,参考欧洲规范中组件法的相关理论,列举了钢框架梁柱节点转角的定义及其主要组成成分,比较分析了目前国内外学者提出的钢框架梁柱节点转角测量计算方法及其在框架结构分析计算中的力学模型,为准确分析计算节点性能及其转角对钢框架受力性能的影响提供参考。
The corner of the beam-column joint of steel frame has an important influence on the internal force and deformation of the steel frame and the design of the beam-column member. The bending moment-rotation (M-) curve obtained from the test or computer simulation is one of the most important bases for analyzing the influence of joint performance on the mechanical behavior of steel frames. The force state and deformation of each component of the joint are studied. Reference to the relevant theory of the component method in the European norm, the definition of the corner of the beam-column joint of the steel frame and its main components are listed. The current domestic and foreign scholars’ The calculation method of the angle measurement of column joints and its mechanical model in the analysis and calculation of the frame structure provide reference for accurately analyzing the influence of the performance of the calculation nodes and the corner on the stress behavior of the steel frame.
