Mejora de la evaluación de la sostenibilidad de puentes en entornos agresivos mediante la decisión grupal multicriterio

Abstract

The construction industry is increasingly recognized as critical

in achieving Sustainable Development Goals. Construction

activities and infrastructure have both beneficial and non

beneficial impacts, making infrastructure design a focal point

of current research investigating how best to contribute to

sustainability as society demands. Although methods exist to

assess infrastructures’ economic, environmental, and social life

cycle, the challenge remains in combining these dimensions

into a single holistic indicator to facilitate decision-making.

This study applies four decision-making techniques (ANP,

TOPSIS, COPRAS, and VIKOR) to evaluate five different design

alternatives for a concrete bridge exposed to a coastal

environment. The results indicate that concretes containing

even small amounts of silica fume perform better over their

life cycle than other solutions usually considered to increase

durability, such as water/cement ratio reduction or concrete

cover increase.
