| 摘 要： | 免蒸压免烧结粉煤灰多孔砖是一种新型承重墙体材料。本文通过三片墙体低周反复荷载试验,系统研究了粉煤灰多孔砖墙体的力学性能和抗震性能,包括墙体的破坏特征、滞回曲线、刚度、延性、骨架曲线及受剪承载力等。试验结果表明,免蒸压免烧结粉煤灰多孔砖墙体的破坏形态与普通黏土砖墙体相似,主要呈剪切破坏;墙体具有较高的受剪承载力、延性和耗能能力,适宜在地震区村镇建筑中推广应用。

| Abstract: | Non-autoclaved and non-sintered fly-ash perforated brick is a kind of new material for load-bearing walls.In order to testify the seismic performance of fly-ash perforated brick wall,the low cyclic load test of three fly-ash perforated brick walls were conducted.The mechanic and seismic performance of fly-ash perforated brick walls including damage characteristics,hysteresis curve,stiffness,ductility,skeleton curve and sherar strength of the walls were studied systematically.The experiment results show that the failure of fly-ash perforated brick wall is similar to sintered clay brick wall,and the featuring failure is mostly the shear failure.The fly-ash perforated brick wall has high shear strength,good ductility and energy dissipation capacity and will be appropriate to village and town buildings of seismic zone. |
