    摘要：局部受压是砌体结构设计的一项重要内容，但其计算理论长期没有新的进展。基于Abaqus软件分析了砌体局部均匀受压情况下的应力、承载力等。结果表明：竖向压应力从局部受压作用面处向周边、向深处变小，发生了力的扩散现象，有限元方法与按GB 50003—2011计算得到的局部抗压强度提高系数吻合较好，研究成果可为砌体局部受压承载力的计算理论改进提供参考依据。

    Abstract：The local compression is one of the important contents in the design of masonry structures. However，there has been no new progress in its calculation theory for a long time. Based on the Abaqus software，the stress and the bearing capacity of masonry have been analyzed under the local uniform compression. The results show that the vertical stresses become small from the local compression face to the surrounding，to the depths，it occurred diffusion of force，the finite element method and compute according to GB 50003—2011 are in good agreement for the increase coefficient of the local compressive strength. The research results can provide some basis for the improvement of the calculation theory of the local compression bearing capacity of masonry.
