FOREWORD

This report documents the finite element modeling of a bolted steel girder field splice connection designed using the traditional method and using a new method that makes conservative assumptions resulting in a simpler, streamlined procedure. The results of the analysis demonstrated the efficacy of the new design procedure, which resulted in fewer bolts compared to the traditional design approach, making the connection more economical. The results of this work would benefit those interested in behavior of bolted connections used for the construction of steel bridges, including State transportation departments, researchers, and design consultants.

16. Abstract

This report documents the finite element analysis of a bolted field splice connection from a hypothetical three-span continuous bridge with back spans 234 ft long, and a 300-ft center span. The connection was designed using a traditional approach and then by using a new simplified method that required fewer bolts for the web splice component. The results of the analysis demonstrated the efficacy of the new design method in that it did not result in overstressing of the girder or bolts at the strength limit state. In part because of this work, the American Association of State and Highway Transportation Officials voted in June 2016 to adopt a new design method for the design of bolted connections for steel bridges.
