摘要
本文借鉴了前人的试验研究,在假定砌体单元为材料主方向的正交各向异性体的基础上,建立了应力增量和应变增量关系式。并应用正交各向异性体弹性常数转换方法,推导出在应力主方向的切线刚度阵,并由此建立了砖砌体双向受力单元非线性分析模型,应用于墙梁结构计算,与试验结果比较吻合。
On the basis of the early days experiments, the relation of the increments of stress to the increments of strain is proposed for the two way forced elements of masonry by assuming orthogonal anisotropy materail in the directions of mortar joint and the matrix of stiffness is presented which represents the increment relation in the directions of main stress by translation of elastic constants of orthegonal anisotropy mater-ail. The nonlinear analysis model of the elements of masonry is used to calculating the wall beams. It has been shown that the calculated results are approximately to those agree with the tested.
