摘要

为使钢筋混凝土剪力墙在多层房屋中更合理的被使用,本文研究了八片分布筋配筋率在0.13%～0.23%之间的钢筋混凝土墙在低周反复加载下的受力性能。较系统的分析了其承载力、延性、刚度及其退化、耗能、破坏机制和破坏特性等。试验表明,该类配筋率墙体完全可以满足多层房屋结构抗震性能要求。
To find a more reasonable way for the use of reinforced concrete shear walls(RC-shear wall)in multi-story buildings,this paper researches the mechanical behavior of eight RC-shear walls with distributed reinforcement ratio between 0.13% and 0.23% under low-frequency quasi-static cyclic loading.Load-carrying capacity,stiffness and its degradation,ductility,hysteretic behavior,energy dissipation and failure phenomena of the shear walls are systematically analyzed.The results show that such walls with low reinforcement ratio are able to meet the requirements of seismic design for multi-storey building through rational design.
