以板端砌体为研究对象,进行有限元非线性分析。分别考虑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压应力分布的影响,建立相应的模型,得出板端砌体局压应力分布曲线,拟合出局压应力计算公式及板端有效支承长度,为工程设计提供参考依据。 Taking the plate-end masonry as the research object, the nonlinear finite element analysis is carried out. Considering the influence of different span, the structure of different joints of floor and masonry on the distribution of local compressive stress of single-span unidirectional slab end masonry under no upper load, the corresponding model is established, End masonry pressure distribution curve, fit out of the formula for calculating the compressive stress and effective support length at the board end, to provide a reference for engineering design.
