| 摘 要： | 通过4个框架顶层T型中节点在低周反复循环荷载作用下的试验,调查了节点裂缝分布特征、抗剪强度、变形性能等抗震性能指标.结果表明:由于梁纵筋在节点内的黏结劣化以及节点箍筋约束效果的下降,T型节点抗剪强度与形状相同的框架中间层├型边节点相比平均降低15%以上.本研究对Hwang的STURT-TRUSS计算模型中的斜压杆机构高度、节点箍筋有效面积等关键解析参数进行了整合,建立了适合于T型节点抗剪强度的计算模型.计算结果与试验结果吻合.

| Abstract: | Based on the experiment of four RC T-shaped interior joints on the top story of a building frame under statically cyclic loading,the indexes of the earthquake-resistant performance of the joints such as crack patterns,shear strength,deformation features etc.were investigated.The experimental results showed that the shear strength of T-shaped joints is 15% less than that of extrior joints due to the affect of beam bar bond deterioration in the joints and confined effect deterioration from joint shear bars.Ba... |
