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.
Traditional Design Approach – 2 Categories. Curved or severely skewed bridges. V-Load, 2D, or 3D analysis. Analysis results include cross-frame forces. Significant DL and LL forces. Cross-frame strength and stiffness OK by inspection.
This chapter provides practical information regarding the decking options and design considerations for steel bridges, presenting deck types such as concrete deck slabs, metal grid decks, orthotropic steel decks, wood decks, and several others.
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.
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
1 sty 2001 · The design stage for curved steel I-girders during casting the concrete bridge deck slab—when the unshored non-composite steel section must support the wet concrete—is not addressed in North American Specifications for bridges. Steel I-girders are flexible in torsion.
