Abstract :
[en] In architectural and construction practices, there is a need for decision-support systems that include disassembly evaluation in the early design and deconstruction stages of buildings. Despite the growth of simulation programs over the past decade, there are no ready-to-use applications for deconstruction potential evaluation. Furthermore, the majority of available tools focus on analyzing building environmental performance while ignoring the technical issues of connection disassembly. In this paper, an expert system has been developed to classify the connections in demountable buildings. The expert system was applied to case studies of newly constructed circular buildings to evaluate their disassembly potential. Disassembly criteria and barriers were identified by reviewing the literature. The fieldwork included the observation of more than 2500 connection systems in this circular building via standardized inspections. A statistical analysis of the disassembly barriers observed during these inspections was presented, and their most probable connections' ability to dismantle was evaluated. The interpretation of this data allowed the creation of an inventory of the measures to be implemented to ensure ease and quality of disassembly, helping the practicing engineer and the disassembly team in their practice. This proposed expert system is considered a first step toward a thorough understanding of the impact of Design for Disassembly criteria and barriers on circularity. Its development in the future will contribute to accurately forecasting the disassembly potential of buildings and material recoverability.
