【提要】  通过试验研究了混凝土多孔砖砌体的弯曲抗拉强度。试验和分析研究表明：混凝土多孔砖砌
体的弯曲抗拉强度试验平均值要低于粘土实心砖砌体的弯曲抗拉强度平均值，但要高于混凝土空心砌块砌体。还提出了混凝土多孔砖砌体的弯曲抗拉强度计算公式并通过对试验结果的线性回归分析确定了公式中的系数。

Abstract:The flexural tensile strength of perforated concrete brick masonry is studied by
 experiment.It is shown that the average values of flexural tensile strength of perforated c
oncrete brick masonry is smaller than that of solid clay brick masonry,but greater than that of concrete building block masonry. And then, the formula of flexural tensile strength of perforated concrete brick masonry is introduced on the basis of test results, also the coefficient in the formula is determined by linear regression of the experimental results.
