摘　　要：目的研究采用不同方式砌筑的A类蒸压加气混凝土砌块砌体轴压试件和通缝抗剪试件的基本力学性能,为工程设计提供科学依据.方法对A类蒸压加气混凝土砌块砌体的24个轴压试件和36个通缝抗剪试件进行试验并对结果进行分析.结果A类蒸压加气混凝土砌体对砌块的抗压强度利用率较高,轴心受压砌体的抗压强度为砌块抗压强度的70%左右.结论在灰缝中配钢筋和纤维能显著地提高抗压砌体的开裂强度,延缓抗压砌体开裂,提高其延性.专用砂浆提高了砂浆与砌块的协调工作能力.砌体的轴心抗压强度与MU10黏土砖、M5混合砂浆砌筑的砌体强度相当.The Purpose of this paper is studying the mechanical properties of axial compression and shearing of suture masonryed by A-type autoclaved aerated concrete block masonry in different ways. Carrying the experiment on 24 axial compression and 36 shearing of suture masonryed by A-type autoclaved aerated concrete block masonry, the result is analyzed. Compressive strength of A-type autoclaved aerated concrete block is highly used and axial compression strength of masonry is about 70% of compression strength of block. The mortar joint with fiber and steel bar can delay cracking, greatly enhancing the deformation capacity of masonry and also improve the brittle nature of the block. Special mortar can improve the oniously working capability of mortar and block. The axial compression strength of A-type autoclaved aerated concrete block masonry is equivalent to masonry with MU10 clay brick and M5 mixed mortar.
