Quality management of structural repair of traditional timber roof structures

As framework was developed based on a literature review of methods and techniques for the structural assessment of traditional timber structures. Taking into account the need for a system approach as the basis for management and maintenance (embedded in the approach of preventive conservation and the ISCARSAH principles: anamnesis, diagnosis, therapy and controls), the framework takes into account the timber characteristics that influence the structural behavior of timber structures, the complexity of traditional structures and the importance of knowledge and experience. It forms the basis for developing a more adapted approach for the assessment of the quality and long-term durability of the structural repair of traditional roof structures. The applicability of the framework is investigated based on two case studies: the gatehouse of the Abbey of Tongerlo (Westerlo, Belgium) and the former church San Carpoforo (Milan, Italy).
