An overview is given of the common floor systems used in multi-storey structures, providing typical framing layouts, typical member sizes and construction depths. Detailed guidance is given on the design of the bracing system in accordance with Eurocode 3, with particular attention to allowance for second order effects. Guidance is also given on
Bracing for construction. The staged construction of composite bridges usually demands more extensive bracing, to stabilise the primary members before the deck slab is complete, in addition to the bracing needed for the service condition.
Bracing is most eficient when placed at angles between 30° and 60°. With steeper bevels, the end connections can be cumbersome. Any brace configuration can be used to make up a horizontal bracing system, as long as a complete load path is available to transfer the load into the lateral load resisting system.
In a braced frame building, the resistance to horizontal forces is provided by two orthogonal bracing systems: Vertical bracing. Bracing in vertical planes (between lines of columns) provides load paths to transfer horizontal forces to ground level and provide lateral stability. Horizontal bracing.
The structure that supports a deck looks pretty simple at a glance. But building a safe and durable deck requires good planning, careful material choices, and attention to detail —especially structural details that are sometimes overlooked by both owner-builders and contractors.
This volume provides: a) an overview of bracing utilized for I-girders, b) a discussion of the bracing systems for tub girders, and c) design requirements for the members and connections of bracing systems.
5 cze 2022 · Horizontal bracing. Vertical bracing (between lines of columns) provides load pathways that carry horizontal forces to the ground level while also providing stiff resistance to overall sway.
