摘要 为研究开洞对装配式砌体填充墙破坏形态和抗震性能的影响,设计了2榀装配式砌体填充墙试件,一榀为普通装配式砌体填充墙,另一榀为开洞装配式砌体填充墙。拟静力试验显示,各试件均为剪切破坏,并且都按照砌块—内肋格—外框格的顺序依次失效,体现出此类墙体具有3道抗震防线;而开洞后试件的承载力、刚度有明显的减小,但对试件的变形能力有所提升,且开洞后墙体试件的裂缝出现提前。最后对装配式砌体填充墙的材料要求、构造措施、承载力和刚度验算等给出了要求。 To study the influence of openings on the failure mode and earthquake resistant behavior of prefabricated masonry infilled walls, two specimens of prefabricated masonry infilled walls are designed, one of which is a common prefabricated masonry infilled wall, and the other is a prefabricated masonry infilled wall with openings. The quasi-static test shows that all the specimens are shear failure, and all of them fail in the order of block, inner rib and outer frame,which shows that such walls have three seismic fortification lines;after the opening, the bearing capacity and stiffness of the test specimen decreases significantly, but the deformation capacity of the test specimen is improved, and the cracks of the wall test specimen appear earlier after the opening. Finally, the material requirements, construction measures,bearing capacity and stiffness checking calculation of prefabricated masonry infill wall are given.
