This study investigates the behavior of link-slab bridges under various angles of skew, boundary conditions, and loadings through the development of 60 threedimensional, finite element bridge models. Models are generated for angles of skew of 0°, 20°, 30°, and 45°. In addition, the models are analyzed under three different boundary conditions. Loads are then applied to the models: positive and negative temperature gradients and three live load patterns, representative of the American Association of State Highway and Transportation Officers (AASHTO) HL-93 loading. The models are analyzed in Abaqus. Accuracy of the analysis models are confirmed with equilibrium, element quality checks, and other visual checks using the pre/post-processor HyperMesh. Trends are then developed as to how forces and moments within the link slab change based on the angle of skew and boundary conditions. Finally, a skew link slab design procedure is proposed.
