“…Optimization methods allow for carrying-out of the decision-making of continuous criteria, where a set of valid solutions are obtained and represented on a Pareto front. Some authors carried out a single-objective optimization, in which the objectives are analyzed separately and then compared [68][69][70][71][72][73]. However, others prefer to apply a multi-objective optimization to get a Pareto set of solutions.…”

Abstract:The construction of bridges has been necessary for societies since ancient times, when the communication between and within towns, cities or communities was established. Until recently, the economic factor has been the only one considered in the decision-making of any type of construction process for bridges. However, nowadays, the objective should not be just the construction of bridges, but of sustainable bridges. Economic, social and environmental factors, which form the three pillars of sustainability, have been recently added. These three factors usually have conflicting perspectives. The decision-making process allows the conversion of a judgment into a rational procedure to reach a compromise solution. The aim of this paper is to review different methods and sustainable criteria used for decision-making at each life-cycle phase of a bridge, from design to recycling or demolition. This paper examines 77 journal articles for which different methods have been used. The most used methods are briefly described. In addition, a statistical study was carried out on the Multiple Attribute Decision-making papers reviewed.

“…Park et al [19] suggested an optimization technique for steel reinforced concrete columns in high-rise buildings that simultaneously considers the structural cost and CO 2 emissions at the structural design phase. Yeo and Potra [20] carried out a similar study for RC moment frames, while Medeiros and Kripka [21] proposed the minimization of monetary and environmental costs of rectangular RC column sections. The work of Fernandez-Ceniceros et al [22] presents a decision criterion based on the embodied CO 2 and the overall cost of one-way floor slabs.…”

Regarding the material, high strength concrete is used as well as self-compacting concrete in beams.Results provide engineers with useful guidelines to design PC precast bridges. The analysis also revealed that reducing costs by 1 Euro can save up to 1.75 kg in CO 2 emissions. The parametric study indicates that optimal solutions in terms of monetary costs have quite a satisfactory environmental outcome and differ only slightly from the best possible environmental solution obtained.
