| 摘 要： | 提出一种全新的钢管混凝土柱 -梁节点形式 .其主要特点是 :采用柱钢管在梁柱节点区不直通、梁纵筋或型钢在节点区连续直通的连接构造形式 ,柱钢管在节点区不连续而导致其轴向承载力的下降通过采用环梁加大节点区截面并配置水平钢筋网或环形钢筋来加强 .通过试验结果证明了采用水平钢筋网加强的这种新型节点的可行性 ,并对节点区的加强水平钢筋网的受力特点进行了讨论

| Abstract: | A new type of column_beam joint of concrete filled steel tubular (CFST) is presented. The main characteristic of this joint is that the steel tubular is discontinuous in the joint zone while the longitudinal steel bar or shaped steel is continuous. Because the discontinuity of the column in the joint zone leads to the decrease of the axial capability, the ring beam is used to enlarge the joint zone and the horizontal reinforcing mesh is used to strengthen it. The feasibility of the new type of joint with horizontal reinforcing mesh is certified by experimental results, and the mechanic feature of the mesh in the joint zone is discussed. |
