软土地基上带圈梁构造柱砌体结构的非线性有限元分析

Nonlinear element analysis of brick masonry structure on soft soil with ring beams and constructional columns

本文对软土地基上带圈梁构造柱的砌墙体进行了非线性有限元全过程分析。根据砌体、混凝土和钢筋各自的本构关系，采用八结点等参元有限元进行求解。在分析过程中，考虑砌体出现的开裂与开裂过程中的应力迁移，讨论了各种工况对墙体的内力分布带来的影响。

The nonlinear finite element is used in this paper for analyzing the brick masonry structure on the soft soil with ring beams and constructional colurnns. According to the respective strain-stress relationship between the masonry structure, concrete, and steel bar,the finite elements of oct-joint are adopted. In the process of analysis, the crack of masonry structure and the transferring of stress are considered.Finally, the influences of working cases are discussed.
