摘要:
为了解钢管混凝土边框内藏钢桁架剪力墙这种新型多重组合剪力墙的抗震性能,进行了3个剪跨比为1.0的低矮剪力墙低周反复荷载试验,包括1个普通混凝土剪力墙、1个圆钢管混凝土边框剪力墙和1个圆钢管混凝土边框内藏钢桁架剪力墙; 对比分析了3个低矮剪力墙的实测承载力、延性、刚度及其退化过程、滞回特性、耗能能力及破坏特征; 使用简化力学模型计算了各剪力墙的承载力,计算结果与试验结果吻合较好。结果表明:圆钢管混凝土边框内藏钢桁架低矮剪力墙的抗震性能比普通混凝土低矮剪力墙显著提高,比圆钢管混凝土边框低矮剪力墙明显提高。
Abstract:
In order to ascertain the seismic performance of the proposed new kind of concrete-filled-steel-tube-column shear wall, an experiment was carried out on three low-rise shear walls with a shear-span ratio of 1.0, including one traditional reinforced concrete(RC)shear wall, one composite shear wall with concrete-filled round steel tube columns, and one composite shear wall with concrete-filled round steel tube columns and concealed steel trusses. Based on the data from this experiment, the load-carrying capacity, ductility, stiffness and its attenuation, hysteretic property, energy dissipation and failure characteristic of each shear wall were contrastively analyzed. The calculated results obtained from the simplified mechanical model were in good agreement with those from the experiment. The results show that the seismic performance of the composite shear wall with concrete-filled round steel tube columns and concealed steel trusses is increased significantly over traditional reinforced concrete shear walls, while at the same time, it shows a significant improvement over composite shear walls with concrete-filled round steel tube columns.
