Brittle Fracture of the Blue River Bridge
This paper describes an evaluation of a brittle fracture that was discovered in one of the welded plate girder members of the I-64 Blue River Bridge in Harrison County of southern Indiana. The study conducted to evaluate the fracture involved a number of different aspects, including a review of previous case histories of cracking at web connection plates, a material testing program to evaluate the strength and notch toughness of the steel, and an analysis of the fracture susceptibility of the detail used in the bridge member. It was found that a number of factors were responsible for the brittle fracture: a small lateral gap between weld toes in the region between the vertical connection plate and a horizontal gusset plate, a sustained period of very low temperatures, and a poor welding detail that initiated a prior fracture in the horizontal attachment plate that resulted in a loss of positive attachment.
