| 摘 要： | 通过对3个1/3比例钢筋混凝土框架异型中节点试件的低周反复荷载试验,分析异型节点的破坏特点、刚度退化和滞回耗能等力学性能,重点研究增加节点区配箍率、梁垂直加腋等配筋构造措施对异型节点抗震性能的影响。研究结果表明:小梁底部垂直加腋后试件在小梁与加腋界面处发生弯曲破坏,延缓节点区的剪切破坏,从而改善异型节点的抗震性能。

| Abstract: | According to the experimental investigation on three specimens of abnormal interior joints under low cyclic reversed loading,the failure process and patterns were obtained.The failure characteristics,mechanical behaviors of abnormal joints such as the load displacement hysteretic loops,rigidity deterioration and energy dissipation were analyzed.The experimental study was conducted that focused on the effect of joint hoop percentage and vertical haunched beam on seismic behaviour of abnormal joints.Test resu... |
