Design for Deconstruction Applied to Reinforced Concrete Building Structures: Design Guidelines Focused on Circularity
Year: 2025
Type: article
Abstract: Objective: This study aims to propose structural design guidelines that support the deconstruction of reinforced concrete buildings, promoting sustainable practices of material reuse and recycling at the end of their service life. Method: A qualitative approach was adopted, including reviewing national and international literature and administering questionnaires to 15 industry professionals or researchers with expertise in structural engineering and sustainability. The data were organized according to the principles of Design for Deconstruction (DfD): (i) reuse, (ii) disassembly and recoverability, and (iii) maintainability of deconstructability. Results and Discussion: The analysis resulted in technical guidelines addressing adaptability, modularity, use of precast components, detailing of demountable connections, extended durability, and standardization. Building Information Modeling (BIM) was also highlighted as an essential tool for ensuring traceability and managing deconstruction processes throughout the building’s lifecycle. While the proposed guidelines are consistent with the literature, some divergences were noted, particularly regarding the optimal scale and complexity of structural elements suitable for deconstruction. Research Implications: The findings provide practical support for structural designers seeking to implement DfD strategies in reinforced concrete structures, fostering circular economy practices within the construction sector. Originality/Value: This study contributes to the literature by expanding the application of DfD to reinforced concrete structures, an underexplored area, by formulating guidelines derived from integrating theoretical insights and professional practice.
