摘要
对新型短肢剪力墙-砌块组合墙体各部分的相互作用、受力模式进行了研究,着重分析了砌块墙的破坏形态、导致破坏的原因。分析表明,组合墙的破坏模式为整体弯曲破坏,混凝土墙肢为拉剪破坏;砌块墙的破坏模式以斜压、剪摩破坏为主,伴随局部压碎及剪压-剪摩复合破坏;与普通连梁相比,组合墙连梁还额外承受由砌块墙反作用的剪力,容易产生剪切破坏。
This paper investigated the working mechanism and the failure modes of the new type of short-pier shear - masonry composite wall, discussed its interaction, work mechanism, especially analyzed the failure pattern mode and the reason of the masonry walls. The results show that the composite wall structure could be equivalent to the whole shear wall because it mainly resists the horizontal load with overall moment. The failure pattern of masonry walls are mostly diagonal compression and shear-friction failure accompany with partially crushed and shear-friction and shear-compression failure. Compared to common coupling beams, composite wall also sustain shear force caused by the masonry wall, which can easily cause shear failure.
