| 摘 要： | 通过对8根剪跨比为3,十字型钢混凝土柱进行了低周反复荷载实验,研究型钢混凝土柱的抗震性能. 主要分析了实验构件的破坏形态、滞回曲线、骨架曲线、延性系数和耗能能力,并探讨了体积配箍率对型钢混凝土柱抗震性能的影响,通过实验数据的拟合给出了型钢混凝土柱的延性与体积配箍率的关系式. 实验结果证实十字型钢混凝土柱构件具有良好的抗震性能,而且体积配箍率是影响型钢混凝土柱构件延性的一个重要因素,对构件的抗震性能的改善具有非常明显作用. |
| 关 键 词： | 型钢混凝土 混凝土柱 抗震性能 延性 |

| Abstract: | In order to study the seismic behavior of steel reinforced concrete(SRC)columns,eight cross-shaped SRC columns with a span ratio of 3 were tested under low cyclic reversed loading.The influence of volume-stirrup ratio on the seismic behavior of SRC columns was discussed by analyzing the failure patterns,hysteresis loops,skeleton curves,ductility coefficients and energy dissipation capacities of such members.A formula between ductility and volume-stirrup ratio of SRC columns was put forward by fitting the ex... |
