HOAN BRIDGE BRITTLE FRACTURE AND RETROFIT DESIGN

On December 13, 2000, 2 of the 3 girders of the northbound Hoan Bridge carrying I-794 in Milwaukee, Wisconsin, developed full depth brittle fractures, leaving the span near collapse. A forensic investigation concluded that the sudden brittle fracture originated in the lower shelf plate joint assembly and traveled the length of a vertical 3.05 m steel I girder in a single cycle. The Hoan Bridge brittle fracture was the first of its kind ever observed in the U.S. and is likely to have an impact on bridges with similar details nationwide. This paper presents an overview of the Hoan Bridge failure, the forensic investigation findings, and the design of the emergency and permanent retrofits.
