【摘要】 钢骨混凝土异形柱是一种新型的结构形式，其集钢骨混凝土结构和异形柱结构体系的优点于一体，具有延性好、承载力高、适用美观等特点。有关钢骨混凝土异形柱抗震性能的试验及研究成果尚少见。本文通过4根L形截面钢骨混凝土柱的低周反复加载试验，得到了L形截面钢骨混凝土柱在压、弯、剪共同作用下的破坏形态，实测了试件的荷载—位移P-D滞回曲线，计算其延性系数μ、等效粘滞阻尼系数he，探讨了轴压比、剪跨比、配箍率对钢骨混凝土异形柱滞回曲线、耗能能力以及延性的影响，并将钢骨混凝土异形柱与钢筋混凝土异形柱进行对比分析。试验结果表明，钢骨混凝土异形柱承载力高、延性好，其抗震性能优于钢筋混凝土异形柱。更多还原

【Abstract】 Steel reinforced concrete special-shaped column is a new structural form. It has all strongpoints of steel reinforced and special-shaped column structure.Bearing capacity and ductility of this new structure is very good, as well as excellent applicable quality and pleasing to the eye. Based on the experiment of 4 steel reinforced concrete of L-shaped section columns subjected to low cyclic reversed lateral loads, the main failure patterns of steel reinforced concrete of L-shaped section columns under compression, combining flexure and shear force are obtained, and then the load-deflection P-D hysteretic loop of all the specimens have been drawn. The ductility coefficientμand equivalent viscous damping coefficient h_e have been calculated. The influence of axial comperesion ratio,shear span ratio, and stirrup ratio on the hysteretic loop, capacity of energy dissipating and ductility of steel reinforced concrete special-shaped column are analyzed.Its have been contrast with each other reinforced concrete special-shaped column and steel reinforced concrete special-shaped column. Test results indicate that steel reinforced special-shaped column have the behavior of high resistant capacity and excellent ducitility, the seismic performance of which is super to that of reinforced concrete columns.更多还原
