为了深入了解构造柱对蒸压粉煤灰多孔砖墙体受力性能的影响,通过对6片蒸压粉煤灰多孔砖墙与1片烧结多孔砖对比墙的低周反复荷载试验,系统研究了蒸压粉煤灰多孔砖墙体的破坏特征、承载能力、耗能能力、滞回特征及刚度退化等抗震性能。试验结果表明: 构造柱对墙体的抗震性能产生显著影响,构造柱墙体耗能能力远大于无构造柱墙体,三构造柱墙体耗能能力大于两构造柱墙体; 竖向压力对墙体的水平承载力影响较大,随着竖向压应力加大,墙体的抗剪强度提高,但破坏脆性加大。基于试验结果,提出了地震作用下带构造柱的蒸压粉煤灰多孔砖墙体的骨架曲线和抗剪承载能力计算方法,计算值与试验结果吻合较好。

In order to understand the mechanical properties of the autoclaved fly ash perforated brick, the pseudo-static tests about 6 autoclaved fly ash perforated brick walls and 1 fired perforated brick wall was concluded. Theseismic performance of walls about failure pattern, hysteresis curve, stiffness, ductility, skeleton curve and shearstrength has been researched systematically. The tests indicate that the failure pattern of autoclaved fly ash perfora-ted brick walls is different from the fired performed brick walls. The constructional column has a material impact onthe seismic performance of th...
