摘　　要：为了解决混凝土砌块砌体剪力墙端部约束区配箍不足的问题,创新研制了在砌块壁内配置箍筋的新型内置箍筋混凝土砌块,并进行了6个内置箍筋的新型砌块砌体试件和2个对比试件的轴心受压试验,充分了解了内置箍筋砌块砌体的受压性能。试验结果表明:采用内置箍筋的新型砌块试件较无约束对比试件破坏模式有很大程度的改善,承载力和极限变形也有不同程度的提高;通过进一步分析计算得出了承载力和极限应变的计算公式;通过对设计实例的计算分析,举例说明了内置箍筋新型砌块对提高砌块砌体剪力墙的承载力和抗震能力具有很强的实用价值。In order to simulate the mechanical performance of the end of block masonry shear wall, 6 specimens with neotype block and 2 comparative specimens were designed and performed under axial compression, rFne result of the experiment shows that the failure model of specimen with reinforced block becomes better than that of comparative specimen. As the volume ratio of reinforcement increases, the bearing capacity and extreme deformation are improved variably, rFne formula of the bearing capacity and extreme strain are offered to application of the practice engineering.
