ABSTRACT The refurbishment of twentieth-century buildings has given rise to lively discussions both at a national and international level over the past 20 years. Such discussions have suggested the opportunity of working on the aforesaid buildings, enhancing what they could afford from a cultural, economic and environmental point of view. Furthermore, underlining how the scope of viable restoration projects is getting wider and wider when compared with the ones targeting pre-industrial buildings. Restoring and refurbishment reinforced-concrete buildings require a different approach from brickwork ones, in order to take into account their different building features and structural behaviour. This has led to setting down specific working guidelines that anyway need to be supported by more adaptable project-related solutions allowing their refurbishment, even as regards their structural reversibility. The refurbishment of the former Excelsior Cinema (1926–30) in Milan presents the features of an operational experiment concerning finding project-related and technical solutions allowing a correct interface between new spaces and existing volumes, even as far as relevant refurbishment of the buildings is concerned. This has made a thorough analysis of the building even more necessary. Furthermore, an experiment has been made regarding a weight-bearing capital enabling the new structures to work together with the existing ones.

钢筋混凝土历史建筑整修的结构可逆性标准和指南。米兰的 Excelsior 电影院（1926-30）

摘要 在过去的 20 年里，20 世纪建筑的翻新在国家和国际层面引起了热烈的讨论。这些讨论表明有机会在上述建筑物上工作，从文化、经济和环境的角度提高他们的能力。此外，强调与针对前工业建筑的修复项目相比，可行的修复项目的范围越来越广。修复和翻新钢筋混凝土建筑需要不同于砖砌建筑的方法，以考虑到它们不同的建筑特征和结构行为。这导致制定了具体的工作指导方针，无论如何都需要得到更具适应性的项目相关解决方案的支持，以允许它们的整修，即使是关于它们的结构可逆性。米兰前 Excelsior 电影院（1926-30 年）的翻新展示了一项操作实验的特点，即寻找与项目相关的技术解决方案，允许新空间和现有体量之间的正确接口，甚至就建筑物的相关翻新而言担心的。这使得对建筑物的彻底分析变得更加必要。此外，还进行了一项关于承重资本的实验，使新结构能够与现有结构一起工作。米兰前 Excelsior 电影院（1926-30 年）的翻新展示了一项操作实验的特点，即寻找与项目相关的技术解决方案，允许新空间和现有体量之间的正确接口，甚至就建筑物的相关翻新而言担心的。这使得对建筑物的彻底分析变得更加必要。此外，还进行了一项关于承重资本的实验，使新结构能够与现有结构一起工作。米兰前 Excelsior 电影院（1926-30 年）的翻新展示了一项操作实验的特点，即寻找与项目相关的技术解决方案，允许新空间和现有体量之间的正确接口，甚至就建筑物的相关翻新而言担心的。这使得对建筑物的彻底分析变得更加必要。此外，还进行了一项关于承重资本的实验，使新结构能够与现有结构一起工作。
