摘　　要：在实验室制作了3个T型钢结构节点试件,通过对结构施加拟静力来模拟地震作用,分析钢结构节点受力过程中的变形规律,并对其受力过程中的滞回曲线进行分析,得出影响节点受力性能的一些规律,同时利用ABAQUS有限元软件对梁柱T形全焊节点进行了模拟分析,研究构件的尺寸变化对节点裂缝的影响,并和试验结果进行对比分析。通过对钢结构节点的试验研究和模拟分析,为研究钢结构节点的抗震性能、破坏特征、探伤及识别做了有益的探索,同时得到了一些具有参考价值的试验数据,总结了提高抗震性能的一些措施。Three T-stub joints were manufactured in laboratory,the quasi-static tests was conducted on the structure to simulate earthquake load and analyze the deformation law of the stress in the process,and the hysteretic curves in the process of stress were analyzed,and some rules affecting the mechanical properties of joints at the same time were summarized. The T-stub fully-welded joints were simulated and analyzed by using the finite element software ABAQUS,the paper studied the effect of member size on joint crack and compared with the experimental results. Through the experimental research on the joint of steel structure and the simulation analysis,a useful exploration was made for the seismic performance of steel structure failure characteristics,detection and recognition,and some valuable experimental data were obtained,some measures to improve the seismic performance of the application were summarized.
