Sustainable Design of Reinforced Concrete Structures: A Multi-Criteria Software-Based Optimization Approach

Abstract:

This paper deals with the multi-criteria optimization of reinforced concrete floor structures in terms of environmental impacts, costs, and durability. A software tool was developed and applied to three structural systems: one-way slabs with beams and girders, slabs supported by beams on all edges and flat slabs. The implemented optimization algorithm is presented, and the influence of span and imposed load on the environmental impacts and costs of the optimal solutions is analyzed. Selected scenarios illustrate the process of identifying the most suitable structural variant. Finally, the discussion highlights practical aspects of structural system selection, where additional criteria such as layout flexibility, acoustic performance, and construction time must be considered.
