Abstract:

This report explains the fundamental concepts behind and provides the design calculations for an ultra-high performance concrete (UHPC) link slab. In this design example, an existing four-span, steel simple-span composite bridge containing traditional expansion joints is used as the base structure. The example steps through the process of designing link slabs that will replace the three interior expansion joints on the bridge. Construction details for the existing structure and link slab design are provided. Calculations are provided to determine the longitudinal horizontal loads for the structure to evaluate the effect of the link slabs on the existing substructure and foundation elements. The redesign of the bearings is also included.
