单边日照对薄壁高墩偏位的有限元分析

Finite Element Analysis on Deflection of Thin Wall High Pier with Single-side Sunshine

结合工程实例,运用有限元软件MIDAS/CIVIL,建立Beam单元和Thick plate单元空间有限元模型,考虑在单边日照下,对薄壁高墩的施工偏位进行有限元分析,结果表明:在单边日照下,对最大悬臂施工阶段高墩的稳定性影响不容忽视。

Combined with the engineering cases, the finite element software MIDAS/CIVIL is used to establish the finite element model of Beam unit and Thick Plate unit. Under the sing side sunshine, the article describes the finite element analysis on the construction deflection of thin wall high pier. The result shows that it is not to ignore the influence on the stability of high pier in the construction period of the longest cantilever under the single side sunshine.
