The behaviour of axisymmetric masonry shells can be simulated by a system of forces constituted by meridian forces acting in the vertical planes, and by hoop forces acting circumferentially. A crucial component for the assessment of these structures using the Modified Thrust Line Method (MTLM) is the determination of hoop forces, whose computation is strenuous, limiting the practical application of MTLM. Working around this limitation, the current research introduces a strategy to manipulate the hoop forces by graphically implementing a function describing their distribution. The adaptiveness of this distribution function not only allows the application of MTLM for the analysis of a range of geometries, but also enables the simulation of membrane behaviour, arch behaviour and their combination, for considering partially cracked structures. Taking this into account, the approach is applied in the case studies illustrated within the current research.

轴对称砌体壳的行为可以通过由作用在垂直平面上的子午力和圆周作用的环向力构成的力系统来模拟。使用修正推力线法 (MTLM) 评估这些结构的一个关键组成部分是确定环向力，其计算量很大，限制了 MTLM 的实际应用。为了解决这个限制，当前的研究引入了一种策略，通过以图形方式实现描述其分布的函数来操纵箍力。这种分布函数的适应性不仅允许应用 MTLM 来分析一系列几何形状，而且还可以模拟膜行为、拱行为及其组合，以考虑部分开裂的结构。
