摘要
在设置垫板的新型钢结构梁-柱T形件连接节点抗震性能试验的基础上,应用有限元软件ABAQUS对此节点进行滞回性能分析。数值模拟与试验结果分析表明:两者吻合较好。利用有限元模型研究几何参数和物理参数对此节点滞回性能的影响,分析结果表明:下部T形件翼缘厚度、梁高和下部T形件翼缘上螺栓的竖向间距对节点的滞回性能影响较大,垫板宽度只影响此新型节点的受压性能。
Based on the innovative beam-to-column T-stub connection with inserted plates seismic test,the nonlinear analysis to this connection was made by the finite element software ABAQUS. The computed results agreed reasonably well with the experimental results. The effects of its components on its hysteretic behavior were analyzed through finite element software. The results show that the thickness of flange of the T-stub at the beam＇s bottom flange,the beam height,the vertical interval of bolts on the flange of the T-stub at the beam＇s bottom flange greatly influence the hysteretic behavior of the connections. The widths of the inserted plates just have some effect on negative mechanical properties of the connections.
