摘　　要：建立了平面外偏心荷载作用下配筋混凝土砌块墙体的截面力学平衡方程,同时引入灌芯混凝土砌块砌体本构关系与平截面假定等条件,推导了配筋砌块墙体平面外偏心受压时的偏心影响系数、稳定系数和承载力影响系数φ,从而建立了相应的承载力计算公式.通过配筋砌块墙体偏压承载力试验数据对公式进行了参数确定,并将计算结果与规范的计算方法进行了对比分析,验证了该方法的合理性与适用性.The sectional mechanical balance equation of reinforced masonry walls with out of plane eccentric load has been presented. Based on the constitutional relation of concrete - filled concrete masonry and the smooth section assume, the influence coefficient of eccentricity, the factor of stability and the influence coeffi- cient of bearing capacity φ of reinforced masonry walls with out of plane compressive eccentric load and the formula to calculate capacity have been got. Some parameters are determined from the test results. The calculated results have been compared with that got from the code method to certify its rationality and applicability.
