The Jean River near Wabush, Labrador is crossed by two railways and an access road by twin 6m diameter culverts . They are heavily strutted inside their barrels to counteract some significant shape deformation, and are deemed not suitable to sustain the increased volume of rail traffic serving the development of the Bloom Lake mines. The owner requested the design and construction of a replacement scheme for an additional design life of 20 years with a time sensitive schedule for completion of the work during the 2013 construction season. This VE concept for the design of live load relief spans …

Risk-Based Bridge Inspection Practices, Rebecca Reising
Risk-Based Bridge Inspection Practices, Rebecca Reising
Open Access Theses
Improving bridge safety, reliability, and the allocation of bridge inspection resources are the goals of the proposed risk based bridge inspection practices. Currently, most bridges in the United States are inspected at a fixed calendar interval of 24 months, without regard to the condition of the bridge. Newer bridges with little or no damage are inspected with the same frequency as older, more deteriorated bridges thus creating inefficiency in the allocation of inspection resources. Because of limited resources, it is not possible to spend the necessary time examining bridges that are in poor condition and require extra attention since equal …

Bridge networks are expensive and complex infrastructures and are essential components of today's transportation systems. Despite the advancement in computer aided modeling and increasing the computational power which is increasing the accessibility for developing the fragility curves of bridges, the complexity of the problem and uncertainties involved in fragility analysis of the bridge structures in addition to difficulties in validating the results obtained from the analysis requires precaution in utilization of the results as a decision making tool. The main focus of this research is to address, study and treatment of uncertainties incorporated in various steps of performance based assessments …
