Abstract:

Steel twin tub girder (STTG) bridges (Figure 1) are a popular choice for dealing with long-spanned bridges in Texas, especially when tight-radii curves are necessary. Such solutions are aesthetically pleasing. However, these bridges are deemed fracture critical; with this comes a high price of biennial inspection. Since the structural members are prone to fatigue and fracture failures, the nonredundant structural elements of fracture critical bridges make these susceptible to sudden total or partial collapse that is initiated by the failure of a single member.
