摘要:
选取4组8个梁柱节点模型,对焊接复合箍筋柱蜂窝梁组合节点进行拟静力试验研究.分析组合节点在模拟地震作用下的破坏形态及承载力,并探讨其抗震性能.试验观测及分析结果表明,在RCS梁柱节点中,箍筋除了抗剪作用外,对约束混凝土、减少节点剪切变形和增加延性均起重要作用; 采用外伸式端板连接的试件,其在柱端低周反复荷载作用下具有较好的延性和耗能能力.通过对比3种节点连接形式发现,钢梁对梁柱节点的转动性能约束越强,则钢筋混凝土柱分配到的水平地震剪力越大,核心区混凝土发生的剪切破坏也越严重.
Abstract:
The eight beam-to-column steel-concrete composite(RCS) joints model of castellated beams with welded compound stirrup are divided into four groups,the quasi-static experiments of eight joints are conducted.The failure modes and bearing capacity of the composite joints subjected to the simulation of earthquake are analyzed,and its seismic performance is discussed.Both the experiment and analysis show that in the RCS beam-to-column joints,stirrups play an important role in confining concrete,reducing the shear deformation,increasing the ductility and increasing the shearing capacity as well.The use of end-plate connections in the test piece,the end of column subjected to the low cyclic loads owns benign ductility and energy dissipation capacity.Comparing the three kinds of joints,it is found that the more rotational restraint of steel beam to joint,the more horizontal seismic force applying to the reinforced concrete column,and the more serious shear failure in the core of joint.
