Rapid bridge construction technology, precast elements for substructures

Abstract

The goal of this research was to propose an alternate system of precast bridge substructures which can substitute for conventional cast in place systems in Wisconsin to achieve accelerated construction. Three types of abutment modules (hollow wall with cap, full height socketed, partial height socketed) are proposed for use in Wisconsin. Design calculation sheets, example designs, and standard type drawings have been provided for the modules. A special design method (in MathCad) and tutorial is provided for detailing reinforcing around the embedded pile in the socket of the abutments.
