摘　　要：通过对混凝土普通砖砌体受压试验结果的对比和分析,讨论混凝土普通砖砌体在竖向压力作用下裂缝的发展特点和变形规律;建立了混凝土普通砖砌体抗压强度的计算公式并提出抗压强度设计值的建议取值。试验研究结果表明,混凝土普通砖砌体具有较高的受压承载力,在正常的使用状态下不会出现裂缝,可成为替代黏土砖的一种新型承重墙体材料。Based on contrast and analysis of the experimental result of concrete solid brick masonry under compression, the devdoping feature of cracks and transfiguration law of concrete solid brick masonry under vertical pressure are discussed. The formula calculating the compression strength of concrete solid brick masonry is given, and the design value of compression strength of such masonry member is suggested. The result of experimental study shows that concrete solid brick masonry has higher compression bearing capacity and crack will not accrue under normal service load so it can be a new bearing wall material substitute for clay brick.
