摘要
对一种GB12337未包含支柱支撑结构形式的3000m3球罐——改进型U形柱支撑球罐,进行了应力分析,并与通常认为受力状态较好的加托板结构支撑的同参数球罐进行了应力分析对比。结果表明,无论从受力状态还是建造合理性方面,其都不失为一种结构优良的球罐支撑方式。
This paper gives the detail stress analysis results for spherical tank of new structure support column named modified U shape support column which not included in code GB 12337--1998. Contrast is also conducted between this new type of support column spherical tank and tanks supported by columns with smaller U - shape plate at underside with same spherical tank design parameter and structure dimension parameter. The results show that this new type of support column is better on stress distribution and structure made.
