Description:

This report explains how to evaluate steel bridge details for susceptibility to constraint-induced fracture. The report begins with a review of fundamental principles of ductile behavior of steel structures and the effects of constraint and stress triaxiality. A brief history of constraint-induced fractures of steel bridges in the United States and a review of published research, policies, and practices is also provided. The report then presents a possible method for evaluating a steel detail for the presence the three conditions associated with elevated susceptibility to constraint-induced fracture: high tensile stresses (including residual stress effects), a high degree of constraint, and planar discontinuities approximately perpendicular to the primary flow of tensile stresses. Next, a series of commonly used steel bridge details are evaluated to illustrate the procedure and to provide a baseline library of evaluations. Redesign, inspection, retrofit, and repair options for problematic details are briefly discussed. The report also presents general design details and construction considerations and possible future research topics.
