girder systems. I-girder and box shaped members are covered. Bracing for other types of bridges, such as truss, arch or towers is not specifically addressed; however much of the information included in this volume may be applicable. Bracing systems serve a number of important roles in both straight and horizontally curved bridges.
This module discusses the design of bracing systems for the superstructures of straight and curved girder systems. I-girder and box shaped members are covered.

Steel Bridge Design Handbook: Bracing System Design. This module discusses the design of bracing systems for the superstructures of straight and curved girder systems. I-girder and box shaped members are covered.
A bracing system serves to stabilize the main girders during construction, to contribute to the distribution of load effects and to provide restraint to compression flanges or chords where they would otherwise be free to buckle laterally.
Internal Bracing Requirements of Horizontally Curved Box-girders. Chai H. Yoo1 , Junsuk Kang 2, Kyungsik Kim3. Abstract: The trapezoidal box (tub) girder is frequently used for horizontally curved highway bridges because of its high torsional rigidity.
The guide provides design criteria, commentary, and example designs. It is also intended to show bridge designers how to implement lean-on bracing in routine bridge designs with confidence and with minimal computational effort beyond that required for a traditional bracing system.
