［摘要］對底層局部框架的典型混合結(jié)構(gòu)體系農(nóng)居進(jìn)行單軸振動臺模型試驗(yàn)，結(jié)果表明，該類農(nóng)居的震害主要集中在房屋底層墻體和構(gòu)造柱，帶窗洞橫墻最先破壞并出現(xiàn)斜向裂縫，試驗(yàn)現(xiàn)象與歷次地震中類似房屋的破壞情況較為一致。在試驗(yàn)基礎(chǔ)上提出了對該類農(nóng)居抗震設(shè)計(jì)和加固的一些建議，其中底層構(gòu)造柱的合理布置和對底層墻體進(jìn)行加強(qiáng)是提高該類農(nóng)居抗震能力的有效方法。

Abstract:Uniaxial shaking table model test was carried out on typical rural residential of hybrid structural system with local frames in bottom layer. Results show that the damages of this kind of rural residential in the earthquake mainly concentrate in the bottom walls and structural columns. Transverse walls with window holes fail first with inclined cracks appeared. Experimental phenomena of the residential are consistent with damage conditions of similar residential in the earthquakes. On the basis of the experiments, some suggestions of seismic design and strengthening on this kind of rural residential were presented. The effective methods to improve the seismic capacity of this kind of rural residential include rational layouts of structural columns in bottom layer and strengthening walls in bottom layer.
Keywords:seismic performance; rural residential; hybrid structure; shaking table test
