摘要:
为研究不同轴压比和边缘构件中的箍筋形式对碳纤维增强复合材料(CFRP)筋/钢筋混凝土剪力墙抗震性能的影响，设计了6个剪跨比为2.0的CFRP筋/钢筋混凝土剪力墙，其中3个剪力墙的边缘构件中配置矩形复合箍筋，另外3个剪力墙的边缘构件中配置圆形箍筋，完成了轴压比分别为0.17，0.26，0.33的剪力墙低周反复荷载试验，研究了剪力墙滞回曲线和骨架曲线的特征、强度和刚度退化规律及耗能能力等。结果表明：轴压比和边缘构件中的箍筋形式对剪力墙抗震性能影响较大，随着轴压比的增大，剪力墙承载能力和耗能能力增大，刚度退化程度减缓，但是极限荷载对应的变形和极限变形有所降低；箍筋形式对剪力墙的极限承载力影响较小，但是配置矩形复合箍筋的剪力墙比配置圆形箍筋剪力墙有较大的极限变形，累积耗能能力也较高；轴压比较大时，剪力墙的裂缝发展高度减小，墙角混凝土破坏区域增大，配置圆形箍筋剪力墙墙角混凝土破坏区域和破坏程度比配置矩形复合箍筋的剪力墙大；所有剪力墙的残余变形较小，自复位性能良好。
Abstract:
In order to study the impact of axial compression ratio and the form of stirrup in the edge column on seismic performance of shear walls reinforced with carbon fiber reinforced polymer (CFRP) bars and steel bars, 6 shear walls reinforced with CFRP bars and steel bars with the aspect ratio of 2.0 were designed. The 3 shear walls had rectangular stirrups, while the other 3 shear walls had circular stirrups. These specimens with axial compression ratio of 0.17, 0.26 and 0.33 were tested under reversed cyclic lateral loading. The characteristics of hysteretic curves and skeleton curves, laws of stiffness and strength degradation and energy dissipation capacity of shear walls were researched. The results show that the axial compression ratio and the form of stirrup have significant impacts on the seismic performance of shear walls. When the axial compression ratio increases, the bearing capacity and dissipation capacity are enhanced and the extent of stiffness degradation is mitigated, however the deformations corresponding to the ultimate load and the ultimate deformation go down. The form of stirrup has less influence on the ultimate bearing capacity, but the shear walls with rectangular stirrups have lager ultimate deformation and better cumulative energy dissipation capacity than those with hoops. When the axial compression ratios are bigger, the shear walls have lower depth of cracks and bigger failure regions. The failure region and failure degree with circular stirrup are bigger than those with rectangular stirrups. All shear walls have small residual deformation and good selfcentering performance.
