【摘要】：梭柱节点是传统风格建筑的特点之一,通过对采用矩形型钢混凝土柱与钢筋混凝土圆柱(SRC-RC)梭柱节点和方钢管混凝土柱与钢筋混凝土圆柱(CFST-RC)梭柱节点两种不同梭柱节点的低周反复荷载试验,比较了不同类型梭柱节点在不同轴压比下的受力性能,研究了其承载能力、破坏形态、滞回性能、耗能能力、变形及延性。试验结果表明:SRC-RC梭柱节点和CFST-RC梭柱节点在试验过程中均发生弯剪破坏;各组构件的滞回曲线均比较饱满,在试验过程中均表现出良好的滞回性能及耗能能力,抗震性能优于普通钢筋混凝土梭柱节点;轴压比的变化对于梭柱节点的极限承载力和延性有一定影响;CFST-RC梭柱节点比SRC-RC梭柱节点具有更好的抗震性能。
[Abstract]:The node of shuttle post is one of the characteristics of traditional architecture. The low cycle cyclic loading tests were carried out on the joints of rectangular steel reinforced concrete column and reinforced concrete column (SRC-RC) shuttle column and square steel tubular column and reinforced concrete column (CFST-RC) shuttle column. The load-bearing capacity, failure mode, hysteretic performance, energy dissipation capacity, deformation and ductility of different types of shuttle column joints under different axial compression ratios were studied. The experimental results show that both SRC-RC shuttle column joints and CFST-RC shuttle column joints are subjected to flexural shear failure during the test. The hysteretic curves of each group of members are full, the hysteretic performance and energy dissipation capacity are good in the test process, and the seismic performance is better than that of ordinary reinforced concrete shuttle column joints. The variation of axial compression ratio has certain influence on ultimate bearing capacity and ductility of shuttle column joints, and CFST-RC shuttle column joints have better seismic performance than SRC-RC shuttle column joints.
