经过地震灾害考察,发现砖混结构房屋在地震灾害中破坏最为严重,常为剪切破坏形态,而有少部分的砖墙发生弯曲破坏。本文试通过在窗间墙设立防震缝,使得普通砖墙在地震作用下,将墙身内能量耗散,避免发生房屋倒塌的典型剪切破坏。试验结果验证了防震缝的设置可以使砖墙发生弯曲破坏,为震后的救援工作提供宝贵时间。
After the earthquake disaster investigation, we found that the masonry-concrete houses have the most serious damage in the earthquake disaster and often have the form of shear failure. However, a small part of the brick wall is bent and damaged. In this paper, through the establishment of anti-seismic seam in the window of the window, ordinary brick wall under earthquake action, the wall energy dissipation, to avoid the occurrence of a typical house collapse collapse. The test results verify that the setting of the anti-seismic seam can bend and damage the brick wall and provide valuable time for post-earthquake rescue work.
