This volume discusses the design of bracing systems for the superstructures of straight and curved girder systems. I-girder and box shaped members are covered.
8 gru 2020 · Here, the user can allocate the materials and section properties of the deck, girder, and bracing along with the deck thickness. Furthermore, the user can input detailed superstructure shapes such as the number of girders and the position of girders.
This document focuses on three major components of cross-frame design: (i) analysis techniques, (ii) combining force effects including stability bracing requirements, and (iii) estimating the capacity/resistance for all relevant limit states.
design of a typical three-span continuous straight non-skewed steel I-girder bridge with spans of 140.0 feet – 175.0 feet – 140.0 feet. Specifically, the example illustrates the design of selected critical sections from an exterior girder at the strength, service and fatigue limit states. Constructability checks,
Torsional brace strength requirements for steel I-girders. Yangqing Liu1, Matthew C. Reichenbach2, Todd A. Helwig3. Abstract. Torsional bracing is often used to stabilize beams in building and bridge applications. The bracing improves the stability by restraining twist of the cross section.

composite beam and slab deck Bracing at supports Bracing at intermediate and end supports is required to provide torsional restraint to the girders and to effect the transfer of lateral forces (e.g. collision loads) from deck level to the bearings. The bracing system may also offer vertical support to the end of the deck
