Abstract: The keynote is focused on the implementation of innovative design and optimization strategies for solving multi-criteria problems, in which the structural design of civil buildings complies with the sustainability goals of this century. Moreover, resilience aspects in structure and infrastructures will be discussed with reference to monitoring and control.

The first part of the discussion will include also the Greece's Polyfytos viaduct, the nation's second-longest bridge spanning 1,372 meters, renowned also for providing access to key power plants in South-East Europe. The study has interdisciplinary aspects, considering not only different technological solutions but also LCA and LCC, along with a study of quantifying the resilience of the different solutions under investigation. Thus, the focus in reinforcement and retrofitting solutions is not purely on technical aspects but associates considerations related to economic and environmental costs, and the overall resilience of the solution. So the design proposal that emerges is characterized by a holistic and multidisciplinary approach for transportation infrastructure that in many countries around the world is facing these kinds of issues related to aging and capacity degradation.

The second part of the discussion will focus on a Genetic Algorithm and the well-known one-dimensional bin packing problem (BPP) within a structural optimization process for civil engineering structures. The Objective Function formulation lies in a marked change of the paradigm, in which the target function is represented by the amount of steel required by the factory instead of the structural cost (e.g. weight). The proposed approach is tested on different steel structures with an increasing number of pieces moving from 2D truss beams to 3D domes. The comparison between the traditional minimum-weight approach and the proposed one has been provided for each case study, highlighting economic and environmental benefits deriving from the latter one.
