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。
Shuttle-shaped column joints are one of the characteristics of the traditional style buildings. There were are two different types of shuttle-shaped column joints,including shuttle-shaped column joint of rectangular steel reinforced concrete column and reinforced concrete cylindrical shuttle column（ SRC-RC） and shuttle-shaped column joint of concrete filled square steel tubular column and reinforced concrete cylindrical shuttle column（ CFST-RC）. Based on the experimental study of the low cycle reversed loading tests of two types of traditional style building shuttle-shaped column joints,the mechanical properties of the joints under different axial compression ratios were compared. The bearing capacity,failure pattern,hysteretic behavior,energy dissipation capacity,deformation and ductility of the joints were analyzed. The experimental results show that the SRC-RC shuttle-shaped column joints and the CFST-RC shuttle-shaped column joints suffer from bend shear failure; the hysteresis curves of different groups of components are full,to show good hysteretic behavior and energy dissipation capacity in the course of the experiment,and the joints have better seismic performance than shuttle-shaped column joint of reinforced concrete; the axial compression ratios had some influence on the bearing capacity and ductility of shuttle-shaped column joints; the CFST-RC shuttle-shaped column joints has better seismic performance than the SRC-RC shuttle-shaped column joints.
