Trade-off analysis, one of the key elements of transportation asset management (TAM), helps decision makers to not only quantify how different resource allocations affect system performance but also investigate the trade-off relationships between cost and performance measures and between different performance measures. In the fast-growing field of TAM, researchers are beginning to quantify the ...

Urban areas are hot spots of flood risk due to how urban development concentrates people and assets into hazard prone areas, reinforcing negative externalities on the welfare residents. Mitigating in environments, however, is challenging. This not only because process generating complex, but objectives city planners, residents and/or developers also multi-faceted. Therefore, there various trade...

This paper presents a computational framework for optimal design of non-prismatic reinforced concrete box girder bridges. The variables include the geometry of the cross section, tapered length, concrete strength and reinforcement of box girders and slabs. These are obtained by the enhanced colliding bodies optimization algorithm to optimizing the cost and again CO2 emission. Loading and design...
