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 investig..View full abstract
