Abstract
With escalating concerns over environmental sustainability, the construction industry is facing increasing pressure to minimize its carbon footprint. This study investigated the embodied carbon assessment and cost implications of simply supported beams constructed from concrete and steel materials. The objective was to provide guidance for structural engineers in material selection, particularly for beam structures. The methodology involved a comprehensive analysis of embodied carbon at different stages of the construction process, including product procurement, transportation, and on-site construction activities. Additionally, a cost analysis was conducted to evaluate the financial implications of the material choices. The findings reveal significant differences in the embodied carbon between concrete and steel beams, with steel beams exhibiting lower carbon emissions for shorter spans, whereas concrete beams are more environmentally friendly for longer spans. Moreover, cost analysis underscores the influence of material selection on the overall project cost, with steel beams generally being more expensive than concrete beams. These results highlight the importance of balancing the structural, environmental, and financial considerations in material selection, ultimately contributing to the advancement of sustainable construction practices.
