Abstract: The behavior of a two‐span composite beam, consisting of a concrete slab shear connected to a steel beam and prestressed near the central support region, was studied experimentally. The test beam was 37 ft (11.28 m) long ...

Abstract: The behavior of partially prestressed composite beams consisting of a concrete slab supported by a steel beam is analytically evaluated. The prestress is introduced in the negative moment regions when the slab acts compositely ...

Abstract: The loss of composite action at the negative moment region for a continuous composite girder reduces the girder’s strength and stiffness. This paper presents an experimental investigation into the use of carbon fiber–reinforced ...
