摘　　要：根据国内大量灌芯混凝土砌块砌体轴心受压试验结果,结合变形协调和静力平衡条件,推导出反映芯柱混凝土与砌块强度比的灌芯砌体轴心受压强度平均值fg,m计算公式。计算结果表明,该公式不仅与试验结果吻合较好,而且还充分反映了灌芯砌体中砌块强度降低而芯柱混凝土强度增加的实际情况。Based on the results of a mass of grouted concrete masonry tests, deformation compatibility and static balance, the mean compressive strength, fg, m, is presented by strength ratio of grouted concrete and block. The calculated results have been observed to not only be in good agreement with trial data, but also reflect decrease in the strength of grouted masonry when the strength of grouted concrete was increased.

关 键 词：抗压强度 灌芯混凝土砌块砌体 变形协调 静力平衡
