| 摘 要： | 钢管混凝土边框组合剪力墙是一种适用于高层及超高层建筑的新型组合剪力墙。轴压比是影响剪力墙抗震性能的一个主要因素,高层建筑底部轴压比较大。本文进行了1/4缩尺的1个普通钢筋混凝土剪力墙模型和1个钢管混凝土边框组合剪力墙模型在高轴压比下的低周反复荷载试验。在试验研究基础上,对比分析了剪力墙的承载力、延性、刚度及其衰减过程、滞回特性、耗能能力及破坏特征,建立了钢管混凝土边框组合剪力墙的承载力计算模型,计算结果与实测结果符合较好。研究表明:在高轴压比下钢管混凝土边框组合剪力墙与普通剪力墙相比抗震性能显著提高。 |
| 关 键 词： | 钢管混凝土 钢筋混凝土 组合剪力墙 抗震性能 高轴压比 |

| Abstract: | Composite shear wall with concrete filled steel tube columns is a new kind of composite shear wall,which is applicable to high and super-high buildings.Axial-load ratio is one of key points to shear wall for resisting earthquake.Axial-load ratio of bottom in high building is high.Experiment studies of the seismic behavior of two 1/4 scale models in high axial-load ratio under low frequency circle load have been done.One model is traditional reinforced concrete shear wall,the other is composite shear wall with concrete filled steel tube columns.Based on the experiment,load-carrying capacity,ductility,stiffness and its degradation,hysteretic property,energy dissipation and failure phenomena of each shear wall are contrastively analyzed.The formulas of load-carrying capacity are worked out.The results obtained from the formulas and those from experiment are in good agreement.The results show that the seismic behavior of composite shear wall with concrete filled steel tube columns has been developed evidently compared with traditional reinforced concrete shear wall in high axial-load ratio. |
| Keywords: | concrete filled steel tube reinforced concrete composite shear wall seismic behavior high axial-load ratio |
