通过对3片不同竖向压应力下的蒸压粉煤灰多孔砖墙体在低周反复荷载作用下的试验研究,分析了竖向压应力对该种材料墙体的破坏特征及其刚度、滞回曲线、延性等抗震性能的影响.试验结果表明:随着竖向压应力的增加,墙体的抗裂性能、极限承载能力均有明显提高,但延性会显著降低.为此,提出了蒸压粉煤灰砖组合墙抗剪强度计算公式,该公式能较好地符合竖向压应力对墙体抗剪强度的影响规律.

Based on the experimental investigation of 3 autoclaved fly ash porous brick masonry wails under cyclic loading with different vertical compress stress, this paper analyzes their failure characteristics, deformation, strength, ductility and force-displacement relations. The results indicate that the higher vertical compress stress can not only increase the walls＇ load-bearing capacity, but also improve their behavior of deformation cracking resistance and shear capacity. Based on that, it puts forward calculation formula for shear strength of ...
