摘　　要：本文以板端砌体为研究对象,考虑了墙体在无上部荷载作用下,不同跨度、楼板与砌体连接处不同节点构造等因素对单跨单向板板端砌体局部压应力分布的影响,建立相应的ANSYS有限元模型,得出板端砌体局部压应力分布曲线,拟合出局部压应力计算公式,从而得到板端有效支承长度,为工程设计提供参考依据。The research about masonry beneath slab-end was carried on in this paper. The local compressive stress distribution of masonry beneath slab-end without loads of super-structures was studied in this paper considering the impact of the factors such as ： different slab spans, different joints of floor and wall. Then, according to the results of finite element analysis, the distribution of local compressive stress,formula of local compressive stress of walls and the effective supporting length were fitted. Those would provide the reference for the engineering design.
