砖砌体非线性有限元分析概述

Overview of Nonlinear Finite Element Analysis of Brick Masonry

在采用ANSYS进行砌体结构非线性有限元分析时,目前还缺乏可以借鉴的普遍性研究结论。论文根据程序特点和研究问题的本质,探讨了ANSYS应用于砌体有限元分析时模型建立、材料本构、破坏准则、迭代算法、收敛准则、预应力的模拟等问题,以典型试验结果为基础,通过算例分析探讨了其适用性,并提出了相关建议。

ANSYS has become an effective tool for finite element analysis of masonry structure,but there are few common conclusions for reference.According to the characteristics of ANSYS and the essence of the analysis,some key problems in finite element analysis of masonry structure with ANSYS,such as structural modeling,material constitution,the damage criterion,iterative algorithm,convergence criterion,simulation of pre-stressing force and so on,are discussed in this paper.Based on the test results of typical masonry structures,the applicability of ANSYS to masonry structural analysis is studied and some suggestions for the application of ANSYS are presented.
