Abstract:

Bridges that are classified as fracture critical by AASHTO require more frequent inspections than other types of

bridges, resulting in greater costs for their maintenance. Several historical events have shown, however, that

severe damage can occur to a bridge without necessarily resulting in its collapse. A primary objective of this

research project was to characterize the redundancy that exists in twin steel box-girder bridges, which are widely

used in Texas and are classified as fracture critical. The main goal of the research was to develop guidelines for

modeling a bridge’s behavior in the event that a fracture of a critical tension flange takes place.

The research carried out under this project included laboratory testing, experimental evaluation of a full-scale

box-girder bridge, and detailed structural analyses. Data gathered from the experimental testing program were

used to validate nonlinear finite element models as well as simplified engineering models. Based on the results of

this research, engineers now have guidelines for modeling the response of twin steel box-girder bridges following

the fracture of one of its girders.
