摘要:
采用有限元软件ANSYS对超长混凝土框架结构硬化阶段的温度应力以及温度作用效应进行非线性分析.针对实际工程中超长钢筋混凝土框架结构建立三维实体模型,对此进行热-结构直接耦合分析,得到结构的温度场与应力的变化特征,以此判断在硬化阶段混凝土结构的控制截面,为超长钢筋混凝土结构采取施工措施和构造措施提供参考,具有实际的指导意义.
Abstract:
In this paper, nonlinear analysis was carried out for temperature stress and temperature effect of over-long concrete by the large finite element software ANSYS. Three-dimensional solid model was made for a super-long reinforced concrete frame structure in practical engineering, and direct thermal-structural coupling analysis was made. The variation feature of temperature field structure and stress was obtained to determine the control section in the hardening stage of concrete. The conclusion can provide reference for structural measures and construction measures of reinforced concrete structure, which has practical guiding significance
