摘要: 对1∶10空腔壳基础模型结构的破裂进行了弹塑性有限元分析、计算值与试验值的比较,说明了计算模型和计算参数基本合理;得到了基础筒壁破裂过程中筒壁应力-应变的变化规律,为烟囱基础的设计提供了理论依据。Abstract: The nonlinear finite element analysis of 1∶10 reinforced concrete wall of a chimney foundation model is carried out.Comparison between the analytic strain and the experimental strain shows that the analytic model and parameters are reasonable.A changing law of the stress-strain during cracking of the foundation wall is obtained, which provides a theoretical basis for the design of the chimney foundation.
