Study of demountable Post‐Tensioned floor system: a step towards circular construction

The construction industry is a significant contributor to global solid waste generation, largely due to conventional building practices that hinder cost‐effective material recovery and reuse. On the contrary, demountable floor systems have gained attention as a sustainable alternative, offering enhanced building flexibility, adaptability and the potential to add or remove structural components without complete demolition. This study investigates the suitability of a demountable post‐tensioned (PT) floor system as a viable solution for promoting design‐for‐disassembly by introducing a design philosophy and investigating the response in order to check its reusability. A comprehensive numerical modelling approach has been developed to replicate the actual behaviour of the system. The findings highlight the potential of demountable PT floor systems to bridge the gap between structural efficiency and circular economy principles in construction industry which will help in advancing sustainable construction practices by reducing demolition waste, extending the service life of structural components and enabling adaptable building solutions.
