Compared to simple masonry walls, numerical modelling of masonry vaulted structures is particularly complex due to their three-dimensional curved geometry and articulated masonry pattern. Moreover, the scarce availability of experimental data makes it difficult to validate numerical models for these types of structures. Recently, the simplified micro-modelling approach has been applied by different authors, despite some intrinsic limits, such as huge numerical effort and adoption of ad-hoc written numerical codes. The aim of this study is to overcome these difficulties by using a commercial software with built-in friction interface models and to validate the proposed simplified-micro model through experimental tests on in-scale specimens of arch and cross vault. The proposed approach has shown promising features: experimental results have been numerically reproduced with a high degree of accuracy, both in case of planar and space structures, with both dry and mortar joints. The final result of the study is a validated modelling strategy that could be confidently applied to real masonry vaulted structures.

与简单的砌体墙相比，砌体拱形结构的三维建模特别复杂，因为它们具有三维弯曲的几何形状和铰接式砌体模式。而且，由于缺乏实验数据，因此难以验证这些类型结构的数值模型。最近，简化的微建模方法已被不同的作者采用，尽管存在一些固有的局限性，例如巨大的数值努力和采用即席书面数字代码。这项研究的目的是通过使用带有内置摩擦界面模型的商业软件来克服这些困难，并通过对拱顶和横撑拱顶的标本进行实验测试来验证所提出的简化微模型。所提出的方法显示出令人鼓舞的特征：在平面和空间结构的情况下，无论是干接点还是灰浆接点，实验结果均已高度精确地数值再现。研究的最终结果是一种经过验证的建模策略，该策略可以确信地应用于实际的砖砌拱形结构。
