[提要]  利用解析方法和試驗(yàn)?zāi)B(tài)分析方法研究了高層磚砌體房屋在地震力作用下的破壞機(jī)制，指出其破壞機(jī)制為彎曲型破壞，這一點(diǎn)與普通磚砌體結(jié)構(gòu)的剪切型破壞機(jī)制是不同的。提出的高層磚砌體結(jié)構(gòu)地震破壞機(jī)制，可供該類結(jié)構(gòu)的抗震設(shè)計(jì)參考。還分析了具有構(gòu)造措施的砌體結(jié)構(gòu)的抗震特性。
[關(guān)鍵詞]  高層磚砌體結(jié)構(gòu) 地震作用 破壞機(jī)制 彎曲變形

 

By using analytic method and mode test method, the failure mechanism of high-rise masonry structure under earthquake has been studied. It is pointed out that the failure mechanism of a high-rise masonry structure is bending deformation failure which is different from the shearing one of an ordinary masonry structure. A precious information for the eaIthquake-resistant design of high-rise masonry structure has been put forward. The earthquake-resistant character of high-rise masonry structure with constructing measure has also been analyzed.
Keywords: high-rise masonry stucture; earthquake; failure mechanism; bending deformation; mode test
