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.
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. The braces provide stability ...
Cast-In-Place Concrete Slab Span standards are available for structures using a 14" or 16" slab depth. These are included in our issued set of C-I-PConcrete Slab Span standards. Steel Beam standards are available for structures with Type W18, W21, W24, W27, W30, W33, W36 or W40 beams.
