Nos acaban de publicar en la revista Environmental Impact Assessment Review (primer cuartil del JCR) un artículo relacionado con la optimización ambiental de grandes puentes basándose en el acoplamiento de múltiples restricciones. El trabajo se enmarca dentro del proyecto de investigación HYDELIFE que dirijo como investigador principal en la Universitat Politècnica de València.
To reduce the pollution emissions of bridges to the environment, researchers need to conduct more in-depth research and design the structure. Today’s architectural, structural, and mechanical engineers pay more attention to funders’ requirements and pursue the maximization of economic benefits. The research begins with establishing a theoretical model of the bridge’s robustness under dead and dynamic loads: applying a Three-Dimensional (3D) solid finite element model, swarm intelligence optimization algorithm, and mathematical model of quadratic interpolation approximation solves the problems of multiple loads, discrete data, and convergence. Based on the establishment and analysis data of the research model, the research and analysis of the optimal topology bridge model are completed, and the optimal structure size is obtained. The carbon emissions from the bridge optimization decreased by 2242.92 t, accounting for 25% of the total emissions. This data is shocking, and it also gives investors and governments a painful reminder that they must pay more attention to the sustainable construction and development of the construction industry and achieve the goal of zero carbon emissions in the construction industry as soon as possible.
