This paper summarizes the recent work by the first author’s research group related to vehicle effects on existing bridges, using reliability based performance assessment. The first part presents a simulation framework of fatigue reliability assessment for existing bridges considering the effects of vehicle speed, road roughness condition, equivalent stress range and the constant amplitude fatig...

A recent trend in bridge construction has been the optimization of the cost-to-performance ratio. The most effective way to optimize the cost-to-performance ratio is to maximize the efficiency of the superstructure. Currently, many bridge engineers and designers favor two- or three- girder plate superstructures, due to their cost advantages. However, research on the performance enhancements of ...

Fibre-reinforced polymer composites (FRPs) offer various benefits for bridge construction. Lightweight, durability, design flexibility and fast erection in inaccessible areas are their unique selling points engineering. FRPs used four applications: (1) FRP rebars/tendons concrete; (2) repair strengthening of existing bridges; (3) new hybrid–FRP bridges with conventional materials (4) all–FRP co...

This paper proposes an innovative method for determining the approximate incremental dynamic analysis curves of semi-isolated bridges, including derivation statistical mathematical formulas. Ultimately, is devised based on primary and limit state tangential stiffness values bridges. The bridges selected this study are two reinforced concrete highway in United States, which have been optimally r...

Hybrid structures, notably bridges, consisting of steel girders and concrete decks, are designed to explo it in the best way the mechanical properties of both materials. In order to guarantee safe, durable and low-cost service of such structures, a long-term quality and a robust connection between steel and concrete must be guaranteed. Even if experience in construction, maintenance and exploit...
