| Abstract | 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. Bracing for other types of bridges, such as truss, arch or towers is not specifically addressed; however much of the information included in this module may be applicable. Bracing systems serve a number of important roles in both straight and horizontally curved bridges. The braces provide stability to the primary girders as well as improving the lateral or torsional stiffness and strength of the bridge system both during construction and in service. Depending on the geometry of the bridge, braces may be designated as either primary or secondary members. The engineer needs to recognize the importance of the bracing systems and bracing member design for appropriates construction and in-service stages. This module provides an overview of the design requirements of the braces so that engineers can properly size the members to ensure adequate strength and stiffness. The module provides: a) an overview of bracing utilized for I-girders is covered, b) a discussion of the bracing systems for tub girders, c) design requirements for the members and connections of bracing systems. |
