有限元法在钢筋混凝土结构分析中的应用

摘要

通过有限元法在钢筋混凝土结构非线性分析中的应用与研究,介绍了混凝土的本构关系,钢筋与混凝土间的关系模型,混凝土单元的裂缝模式和破坏准则以及存在的问题,指出有限元法在钢筋混凝土结构非线性分析中的意义.%Through studying application of finite dement method in RC structure's unlinear analysis, the paper introduces constitutive relation of concrete, relation mode between reinforcing steel and concrete, crack mode of concrete unit and distroying principle, as well as problems. It points out meaning of finite dement method in RC structure junlinear analysis.
