ABSTRACT

In this study, a rigorous assessment approach is proposed in order to promote conservation of cultural heritage instead of partial replacement too often overused in the past. With reference to the XVI–XVII cloisters in the Baths of Diocletian in Rome, in the small cloister, known as Ludovisi’s, the old chestnut timber structure was dismantled and substituted with a new roof made of glued and laminated timber rafters and purlins. In the past 20 years, some of the bays of Michelangelo’s cloister have also undertaken substitution of the roof structure, with new timber elements of chestnut wood. In order to satisfy a comprehensive reliability assessment of the roof structure, as required by the management of the monument, the authors carried out non-destructive measures, experimental full-scale tests, as well as a refined finite element modeling, aiming at the conservation of the historical value of the timber structure.

摘要

在这项研究中，提出了一种严格的评估方法，以促进文化遗产的保护，而不是过去经常过度使用的部分替代。参考罗马戴克里先浴场的 XVI-XVII 回廊，在被称为 Ludovisi 的小回廊中，旧的栗木结构被拆除，取而代之的是一个由胶合和层压木椽和檩条制成的新屋顶。在过去的 20 年里，米开朗基罗修道院的一些隔间也进行了屋顶结构的更换，采用了栗木等新的木材元素。为了满足纪念碑管理要求的屋顶结构的综合可靠性评估，作者进行了非破坏性措施，实验全尺寸测试，以及精细化的有限元建模，
