| 摘 要： | 框架梁柱节点性能研究在国内外已经取得较多的研究成果。由于研究条件和方法的差异,使得这些成果的适用性、可比性存在不足,并影响到其推广应用。基于结构体系优化的趋势和节点刚度研究的深入,对框架节点性能研究成果进行分析,重点评述了弯矩-转角关系中的转角测试技术,指出转角测试存在节点域变形的考虑、转角的定义和组成、测试方法的选择等问题。对节点域剪切变形进行了力学计算和试验分析,说明节点域剪切变形对节点转角的影响不可忽略;针对不同的节点类型和构造,需要明确转角的定义和组成,并选用合适的测试方法,其测试结果才能提供结构分析所需的数据。在此基础上,阐明了建立标准的转角测试方法的必要性和途径。

| Abstract: | It is of theoretical and practical importance to study steel frame beam-to-column joints.Because of the differences in testing conditions and methods,existing literatures are found to be inconsistent,particularly due to different methods used in rotation measurement for beam-to-column joints.Shear deformation of joint panel zone was calculated by mechanical formula and testing data.The results indicate that the influence of shear deformation on joint rotation can not be neglected.Testing data can be used in... |

| Keywords: | steel frame beam-to-column joint panel zone testing techniques definition and composition of rotation |
