为研究不同轴压比下再生混凝土高剪力墙的抗震性能,进行了3个不同轴压比、骨料取代率为100%的再生混凝土高剪力墙的低周反复荷载试验。在此基础上,分析了各剪力墙的破坏特征、承载力、延性和滞回特征。研究结果表明:轴压比对再生混凝土高墙的性能有重要影响,轴压力的增加可提高再生混凝土高剪力墙的承载力,但会降低再生混凝土剪力墙的延性和耗能能力;轴压比适中的再生混凝土高剪力墙,延性较好,滞回环稳定,有良好的耗能能力,破坏形式为弯曲破坏。在实际工程中,通过设定合理的轴压比限值,将再生混凝土高剪力墙应用于建筑结构中是可行的。
In order to study the seismic performance of recycled concrete high shear walls with different axial compression ratios, three cyclic low cyclic loading tests of recycled concrete high shear walls with different axial compression ratio and aggregate substitution ratio of 100% were carried out. On this basis, the failure characteristics, bearing capacity, ductility and hysteresis of each shear wall are analyzed. The results show that the axial compression ratio has an important influence on the performance of recycled concrete high walls. The increase of axial pressure can increase the bearing capacity of recycled concrete high shear walls, but reduce the ductility and energy dissipation capacity of recycled concrete shear walls. Medium pressure recycled concrete high shear wall, good ductility, hysteresis loop stability, good energy dissipation capacity, the damage form of bending damage. In practical engineering, it is feasible to apply recycled concrete high-shear walls to building structures by setting a reasonable axial compression ratio limit.
