The structural analysis of a mirror-type vault, consisting of a single- or double-curvature perimeter and a nearly flat part, is carried out. The vault is similar to a number of hybrid iron (or steel) and masonry vaults built between the late 19th century and the early 20th century to span large halls. The numerical analyses were preceded by an accurate geometrical survey and mechanical tests aimed at evaluating the properties of the materials. Thermography allowed the complex brick pattern of the vault to be detected. The influence of rib-walls (frenelli) and the material anisotropy on the stress and deformation of the vault is discussed. Eventually, attention is focused on one of the segmental vaults in the central part of the structure: it is found that the stress can be safely estimated by assuming its boundary to be fixed.

对由单曲率或双曲率周长和几乎平坦的部分组成的镜像型保险库进行了结构分析。该金库类似于19世纪末至20世纪初在大型大厅中建造的许多混合铁（或钢）和石工金库。在进行数值分析之前，需要进行精确的几何调查和旨在评估材料性能的机械测试。热像仪可以检测金库的复杂砖块图案。讨论了肋壁（frenelli）和材料各向异性对拱顶应力和变形的影响。最终，注意力集中在结构中心部分的分段拱顶之一上：发现应力可以通过假设其边界固定而安全地估算。
