Abstract
Highway bridges are important assets in every infrastructure network. The cost of construction and operation of highway bridges are key issues for bridge engineers. However, in the near future the design of bridges and other infrastructures will require more than compiling with safety requirements according to safety standards and economic constraints. The multidimensional perspective of sustainability requires the combination of current design criteria with other important aspects such as society and environment, usually considering a life cycle approach.
In this work, a framework for an integrated life cycle design of bridges is presented. Specific indicators characterising several aspects of sustainability in bridge design are chosen: (i) environmental impacts, (ii) initial and future costs, and (iii) impacts on users. These indicators are quantified over the complete life cycle of the bridge in a probabilistic based approach. Furthermore, the purpose of this paper is to apply the proposed methodology to a steel-composite highway bridge in order to enhance the unique features of this kind of structures in the pursuit of a sustainable construction system.
