中文摘要：

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。

英文摘要：

After investigation of the earthquake hazards,it is found out that,the most serious damage of the houses of brick-concrete structure in earthquake disaster is generally of shear failure mode,whereas flexural failure occurs for a small part of brick walls. By setting seismic joint for wall between windows,the energy within the common wall body will dissipate under seismic action,thus the typical shear failure of house collapse can be avoided. The test results prove that,the setting of seismic joint can make the brick wall have flexural failure,providing precious time for rescue work after earthquake.
