摘要
为了研究空间中框架加强型T型钢半刚性连接节点的抗震性能,采用拟静力试验方法对强轴方向为加强型T型钢连接件的钢节点进行研究分析,加强型T型钢为楔形。试验结果表明:强轴的滞回曲线比弱轴的饱满,强轴在刚度退化、延性及耗能能力方面都要优于弱轴方向,加强型T型钢可提高节点的变形能力、耗能特性和抗震能力。
In order to research the seismic behavior of semi-rigid connection joints with the reinforced T-stub in spatial middle frame,the quasi-static test method was used to research and analyze the wedge-shaped reinforced T-stub joints in the major axis direction. The experiment results showed that the hysteretic curve of major axis was fuller than that of weak axis,And from the aspect of stiffness degradation,ductility and energy dissipation capacity,the major axis was better than the weak axis. Wedged strengthen T-stub could improve the deformation capacity,energy dissipation and seismic capacity of the steel joints.
