【摘要】 分析了现行砌体结构设计规范中关于垫块下砌体局部受压承载力计算公式的不足，基于偏心受压砌体受力的特点，对现有受压砌体的应力－ 应变关系进行了修正，并提出砌体偏心受压时的应力－应变关系；利用平截面假定和截面平衡条件，推导出刚性垫块下砌体局部受压承载力计算公式，该式具有计算简单、概念清楚等特点，并能与梁端砌体局部受压承载力的计算相协调，且计算结果与试验结果吻合较好，其结果对砌体的受压承载力分析也有参考作用，可供砌体结构设计规范修订时参考更多还原

【Abstract】 This paper analyses some disadvantages of the bearing capacity of masonry under stiffness bearer in China code(GBJ 10-89).Taking into consideration of the characteristics of masonry under eccentric compression,the relationship between stress and strain of masonry under axial compression is revised.Based on the assumption of plain section and balance condition,the formula of local bearing capacity of masonry under stiffness bearer is deduced.The formula has many advantages such as simplicity,clear conception etc.It is found that the calculation results conform well with that of the experiments.更多还原
