Through the experimentation for the physical performance of cfpb masonry under local compression , the author has observed the deformation and failure of cfpbm . based on the mathematical statistics and regression analysis of the experimental data , the author derived a feasible and common formula for counting the cfpbm ' s local compression strength regarding the different local compression locations , analyzed stress distribution of local bearing masonry under beams end , and provided the calculating formula on effective supporting length of beam end in brick masonry . as the results of experiments demonstrate , owing to the cfpb ' s own holes " system , the beneficial effects , the bounding effect of surrounding masonry and the spread effect of force , have not developed completely 试验结果分析表明：由于多孔砖自身的孔洞结构，砌体内部的围箍作用和力的扩散作用未得到充分发挥，局压强度虽较轴心受压强度有所提高，但仍低于同情况下实心砖的局压强度；当有上部荷载作用时，对砌体局压有利的悬臂卸荷作用和内拱卸荷作用均不明显，因此在推导梁端局压强度计算公式时，未考虑此可能存在的有利影响，计算偏安全；局压强度提高系数公式除采用规范公式（二项式）的表达式，还用对数式进行了回归推导，得到了一个较为普遍的公式；论文还对梁端局压的梁端有效支承长度计算公式进行了回归推导。
