带裂缝钢筋混凝土结构的有限元分析

Considering Crack Propagation of Mechanical Finite Element Analysis of Reinforced Concrete Structures

在影响工程结构质量的众多因素中,裂缝所导致的质量问题最为严重。因其具有演变形随着时间的迁移,部分裂缝的宽度和高度也会发生相应的变化,裂缝的等级也会随之提高。给工程整体质量增添了诸多不安全因素。进一步提升工程质量,控制好工程裂缝问题,在进行钢筋混凝土结构有限元模拟时应当积极的考虑到裂缝现象。文章首先从混凝土结构入手,构建钢筋混凝土有限元模型,进而开展混凝土结构有限元分析,希望为建筑工程钢筋混凝土施工提供一些有益的建议,以供参考。

There are many factors influence the quality of engineering structures in the cracks caused by quality problems are most serious.Because it has played deformation over time,crack width and height will change accordingly,crack level will be increased.Adding many unsafe factors to the quality of the whole project.To further enhance the quality of the project,to control the engineering crack problem,should be actively considering the cracks in reinforced concrete structure finite element simulation.Firstly,from the concrete structure,constructing the finite element model of reinforced concrete,and then carry out the finite element analysis of concrete structures,hope for the construction of reinforced concrete Soil construction to provide some useful suggestions for reference.
