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
A new type of concrete-filled steel tubular column-beam joint is proposed.The main features of this kind of concrete-filled steel tubular column are as follows: the column steel pipe is not straight through in the node area of the beam and column, and the continuous longitudinal connection of beam longitudinal reinforcement or section steel is in the node area, The continuous decrease of the axial bearing capacity is reinforced by using the ring beam to enlarge the cross-section of the node area and to configure the horizontal steel mesh or the circular steel reinforcement.The feasibility of this new type of node strengthened by the horizontal steel mesh is proved by the test results The force characteristics of the reinforced horizontal steel mesh in the node area are discussed
