Towards sustainability in post-disaster constructions with a modular prefabricated structure

ABSTRACT In response to the challenges faced by post-disaster construction, the present study endeavours to offer an improved solution in a practical manner. To this end, a critical analysis of modular systems that can be employed in post-disaster construction is conducted, which is succeeded by the set of required features. Considering these features, a system based on modular prefabricated components (MPC) is presented, which effectively eliminates all hitches while demonstrating facilitated solutions. From a practical standpoint, a comprehensive description of the structure’s dimensions, assembly steps and design constraints are proffered, accompanied by primary structural analysis factoring in the highest risk categories. The applicability and limitations of the system in post-disaster scenarios are also discussed in comparison to other modular construction methods. The findings indicate that the system exhibits high levels of disjoint-ability and collectability, flexibility and customisability, developability and repairability, in addition to being cost- and time-efficient. Furthermore, it demonstrates a favourable response to the predicaments posed by post-disaster situations, such as logistics, construction process, safety, seismic behaviour and environmental effects. Overall, this research highlights the applicability and potential of MPC systems in post-disaster construction and delivers a valuable output for policymakers, managers, architects and engineers involved in this regard.
