【摘要】 对底层局部框架的典型混合结构体系农居进行单轴振动台模型试验,结果表明,该类农居的震害主要集中在房屋底层墙体和构造柱,带窗洞横墙最先破坏并出现斜向裂缝,试验现象与历次地震中类似房屋的破坏情况较为一致。在试验基础上提出了对该类农居抗震设计和加固的一些建议,其中底层构造柱的合理布置和对底层墙体进行加强是提高该类农居抗震能力的有效方法。更多还原

【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.更多还原
