N2 - Connections for steel-concrete composite trusses (SCCTs) for bridge applications were investigated. Eight specimens on a scale of 1/3 of the actual bridge were tested under static loading using connections with different gusset plates, including rectangular (RGP), π shape (PSGP), and J shape (JSGP). A detailed account of the design considerations, loading procedure, and experimental parameters is provided. A three-dimensional (3D) finite-element (FE) model was developed to analyze the mechanical behavior of these three composite truss connections. The results of the FE analysis were in good agreement with the experimental results. Both indicated excellent mechanical behavior for the investigated composite truss connections, with sufficient safety factors. The minimum yielding, cracking, and ultimate loads obtained from specimens were 2.65, 2.21, and 3.87 times the design load (907 kN), respectively. All specimens underwent considerable deformation, thereby suggesting satisfactory ductility. The presented overall investigation may provide a reference for the design and construction of composite joints in composite truss bridges. © 2016 American Society of Civil Engineers.
