This paper presents the process of developing a new procedure for estimating the buckling capacity of spherical shells. This procedure is based entirely on the assumptions included in the standard mentioned, EN-1993-1-6 and also becomes a complement of EDR5th by unifying provisions included in them. This procedure is characterized by clarity and its algorithm is characterized by a low degree of complexity. While developing the procedure, no attempt was made to change the main postulates accompanying the dimensions of the spherical shells. The result is a simple engineering approach to the difficult problem of determining the buckling capacity of a spherical shell. In spite of the simple calculation algorithm for estimating the buckling capacity of spherical shells, the results obtained reflect extremely accurately the behavior of real spherical shells, regardless of their geometry and the material used to manufacture them.
本文介绍了一种用于估算球壳屈曲承载能力的新方法的开发过程。该方法完全基于上述标准EN - 1993 - 1 - 6中包含的假设，并且通过统一其中包含的规定，成为EDR5th的补充。该方法的特点是清晰明了，其算法的特点是复杂度较低。在开发该方法时，未尝试改变与球壳尺寸相关的主要假设。结果是一种针对确定球壳屈曲承载能力这一难题的简单工程方法。尽管估算球壳屈曲承载能力的计算算法简单，但所获得的结果极其准确地反映了实际球壳的性能，无论其几何形状以及制造它们所使用的材料如何。
