A Method for Assessing the Flexibility of Buildings to Dismantle and Reuse Their Structural Elements

The aim of the article is to develop and verify a method for assessing building structural solutions in terms of their susceptibility to dismantling and reuse, referred to as circular flexibility. The novelty of the approach lies in its focus on load-bearing elements and the application of a simple Weighted Sum Model (WSM) that enables the comparison of structural solutions already at the design stage. The research question posed is: Does the Weighted Sum Model (WSM) allow for a reliable comparison of the reuse potential of structural elements? The model is based on three criteria: assembly technology, execution technology, and material type. Based on expert evaluations, indicators (WSM bud) were calculated for ten completed European buildings. The results confirmed that the method allows for measurable comparison of structures and can support design decisions. The limitations include the subjectivity of assessments and the need for calibration of threshold values. Further research will involve verifying the method on new buildings and comparing it with other MCDA techniques
