一顺一丁砌体墙契合规律及平面解构理论

引入契合理论分析了平面应力假设下一顺一丁砌体墙的内在契合规律.通过对砌体进行周期性平面分割,对组元（契合形单位胞体也即RVE）进行解构,得到骨骼单元（基本组元）,进而获得基本形,为严格匀质化单元几何分割提供理论依据.探索了RVE与基本组元之间契合关系的数学模式,推导了RVE的边界条件与初始条件,解决了国内相关研究在数值模拟阶段采用的RVE边界条件与初始条件与理论推导存在差异的问题.

Regular tessellation laws and plane deconstruction theory of flemish bond masonry walls

Regular tessellation theory was introduced to analyze inherent laws of flemish bond masonry walls under the hypothesis of plane stress.By doing periodic plane segmentation on masonry and deconstructing components （unit cells of regular tessellation,namely RVE）,bone cells（basic cells） are gotten,and thus the basic shapes,which provides a theoretical basis for the geometry segmentation to the rigid homogenization units.Then mathematical models of the relationship between the RVE and the basic cell have been explored,the boundary and initial conditions of RVE have also been derived.It solves the problem that RVE boundary conditions and initial conditions used in numerical simulation are different from those of the theoretical derivation.
