Abstract: External confinement of concrete by means of high-strength fiber composites can significantly enhance its strength and ductility as well as result in large energy absorption capacity. The confinement mechanism may include ...

Abstract: Testing results of six existing prestressed concrete bridges are used to evaluate analytical methodologies. These bridges cover different span lengths, number of lanes, and skew angles. Strains, load distribution factors, ...

Abstract: The paper discusses a few issues related to capacity rating of existing bridges using field test results. The principles of proof and diagnostic load tests for capacity evaluation are presented through discussing the rating ...

Abstract: The paper presents the results of a study involving the static and fatigue performance of reinforced concrete beams strengthened with externally bonded carbon-fiber-reinforced plastic (CFRP) sheets. The main parameters in ...

Abstract: The impact of six continuous multigirder steel bridges, with overall span lengths ranged from 130 ft to 260 ft (39.62 m to 70.25 m), due to vehicles moving across rough bridge decks is analyzed. Bridges are modeled as ...

Abstract: The objective of the paper is to study the dynamic behavior of multigirder bridges due to vehicles moving across rough bridge decks. The multigirder bridge is modeled as a grillage beam system. The vehicles are simulated ...

Abstract: Fiber-wrapping or encasement of concrete in fiber-reinforced plastic (FRP) shells significantly enhances strength and ductility of concrete columns. However, design of such hybrid systems requires an accurate estimate of ...

Abstract: The impact behavior of multiple vehicles moving across rough bridge decks on seven multigirder concrete bridges with different span lengths is studied. The bridges are modeled as grillage beam systems. The vehicle is ...

Abstract: The slant‐legged rigid‐frame bridge is one type of the most widely used highway bridges. However, very few dynamic characteristics of this type of bridges have been reported. The objective of this paper is to investigate ...
