摘要
本文采用有限元分析方法,对大型储罐网壳顶进行了非线性失稳分析,对比了三角形网壳与双子午线型网壳的抗失稳性能。通过对比发现,在钢材用量相同的情况下,三角形网壳承稳定性载能力要高于双子午线型网壳,为实际工程应用提供了指导。
In this paper, the finite element analysis method is used to analyze the nonlinear instability of the proof of large-scale storage tank, and the anti-instability performance of the triangular reticulated shell and the twin meridian reticulated shell is compared. Through comparison, it is found that the triangular reticulated shells have better stability than the twin meridian reticulated shells under the same amount ofsteel, which provides guidance for practical engineering applications.
