钢骨混凝土L型截面异形柱抗震性能影响因素探讨

Earthquake Resistance Influence Factors of Special-shaped Column of Steel-reinforced Concrete with L-shape Cross Section

通过四根L型截面钢骨混凝土柱在压、弯、剪共同作用下的低周反复加载试验,探讨轴压比、剪跨比、配箍率对钢骨混凝土异形柱滞回曲线、耗能性以及延性的影响,对于异形柱施工具有一定的工程指导意义。

Four steel-reinforced columns with L-shape cross section are exerted low-cycle reversed loads under the action of push, bend and shear. What＇s more, the influences of axle-pressure ratio, shear-span ratio and ration of reinforcement on the hysteresis curve, energy consumption and tensility are illustrated, which is of great significance to construction of special-shaped column.
