当大型储罐拱顶出现体积型缺陷时,最常见的破坏形式是拱顶外压失稳破坏。因此,针对含体积型缺陷的加筋拱顶,对其缺陷发生的最不利位置及拱顶稳定性进行了大量的有限元计算,提出了含缺陷加筋拱顶临界失稳载荷的实用计算公式,以供建立含缺陷加筋拱顶的安全评定方法参考。 When the bulk tank vault appears volume-type defects, the most common form of vandalism is failure of vault external pressure instability. Therefore, a lot of finite element calculations are carried out for the most disadvantageous location of the defects and the vault stability of the reinforced vaults with volumetric defects, and a practical calculation formula for the critical buckling loads of the vaults with defects is proposed , For the establishment of a safety assessment method with reinforced stiffeners containing defects for reference.
