摘要:
提出了一种自保温无砂浆配筋砌块砌体剪力墙，解决了传统砌体剪力墙砌筑需要砂浆砌筑和需要做内墙或外墙保温层实现墙体保温的问题。通过3片不同轴压比试件的低周反复荷载试验，研究了不同轴压比下该墙体的抗震性能和破坏机理，以及轴压比对墙体的破坏形态、滞回曲线、承载力、延性、刚度、耗能性能的影响；根据试验现象及分析结果对墙体的施工和设计提出了建议。结果表明：墙体破坏形态与传统配筋砌体剪力墙基本相似，破坏区域主要集中在墙底4皮砌块范围内，墙体在破坏时能够保持较好的整体性；随轴压比增大，墙体承载力增大，破坏模式由弯曲破坏逐渐变为弯剪破坏；墙体承载力试验值与规范计算值吻合较好。
Abstract:
The self-insulation mortarless reinforced masonry shear wall was proposed, and the problems of traditional masonry shear wall which needed mortar and needed to do internal or external insulation layer to make wall insulation were solved. Three specimens with different axial compression ratios were tested under quasi-static low cyclic loads to investigate the seismic behavior, failure mechanism, and the influences of axial compression ratio on failure modes, hysteretic curves, bearing capacity, ductility, stiffness and energy dissipation. According to the experimental phenomena and analysis results, the suggestions for construction and design of wall were given. The results show that the failure modes of specimens are similar to those of common masonry shear walls, and the damage area is mainly concentrated in the range of four leather building blocks. The walls are able to maintain good integrity when they are broken. The bearing capacity of walls increases with the increasing of axial compression ratio, and the failure mode turns from flexural failure to shear failure. The bearing capacity of test wall is in good agreement with the calculated values.
