Several stages of performance need to be considered during the design of curved I-girders, including both the construction stage and the in-service conditions. Girder stability during the early stages of construction can be difficult to assess becaus

A fracture-critical bridge (FCB) is a structure that is expected to collapse after the failure of an essential tension component. In the positive bending moment region, the bottom flanges of a twin steel box-girder bridge are considered to be fractur

The stability of I-girders during erection can be difficult to assess because of the limited presence of bracing and uncertainty in the support conditions of the girders. The behavior of curved gir...

A fracture-critical steel I-girder bridge was instrumented with strain gauges to estimate the remaining design fatigue life. The two girders on the bridge had extensive fatigue cracking. Continuous, dynamic strain data were collected for nearly 2 mon

Cross frames and diaphragms play an important role in stabilizing straight steel girders. Commonly used connections between these braces and the steel girders can introduce flexibility, which can have detrimental effects on the bracing behavior, part

The design of curved I-girders is complicated because of the many performance stages that must be evaluated, including erection, construction, and in service. Evaluation of girder stability during early stages of construction is particularly complica

The use of punched holes in bridge structures in load-carrying members is not allowed unless the holes are sub-punched to a smaller diameter and then reamed to full size. Some owners allowed full size punched holes in cross frames and lateral bracing
