A precast concrete deck-steel beam-connection (PCSC) connector using ultra-high-performance (UHPC) as post-cast has been proposed to enable rapid on-site construction of assembled composite bridges. This paper aims optimize the structure PCSC connectors finite element (FE) model maximize material utilization and economic efficiency. refined FE comprising bond degradation at steel–UHPC interface...

Pre-stressed steel-concrete composite beams are widely used in bridges around the world. Loads during service life of may cause failure form fracture studs near ends bridge girders. The effect stud on residual static capacity and fatigue girders is not well investigated. Therefore, this study presents numerical investigations into effects progressive shear connectors performance remaining post-...

Experimental investigation was conducted on corroded composite push-out specimens to study the behavior of shear studs subjected to fatigue loading. A total of eight standard EC4 push-out specimens were tested. The expected corrosion rate of test specimens ranged from 0 to 50%. The main purpose of these tests was to determine the fatigue life and the reduction effect caused by the corrosion on ...

This series of experiments aims to characterize the cyclic behavior of cold-formed steel (CFS) stud-to-sheathing connections. This connection provides the key energy dissipating behavior in wood sheathed CFS shear walls, and provides bracing to the studs under gravity and out-of-plane loads. A simple testing rig is developed consisting of two CFS lipped channels facing toe-to-toe connected on t...

This article presents an experimental investigation on the bending capacity of steel-concrete composite truss girder (SCCTG). Four full-scale specimens named CB1, CB2a, CB2b and CB3 respectively, are tested and numerical analyzed. Stress distribution, load-displacement relationship, load-slip relationship and ultimate bending capacity of SCCTGs are investigated. The results show that SCCTG foll...
