3) Bridge railings (parapets), handrails, sidewalk, lighting, and some drainage features. A bridge floor is the entire length of the bridge from the roadway side of the mudwall or pile cap to the other roadway side of the mudwall or pile cap and the entire width from one coping edge across to the other coping edge.

To ensure that a steel bridge design can be safely, economically and reliably executed (fabricated, assembled and erected), designers should be aware of the processes of fabrication and erection, the capabilities and limitations of the steelwork contractor and how the design choices affect those processes.This article provides guidance on design for construction:it generally follows the
Design of Slab and Girder Bridges (With Diagram)Shear and Shear Reinforcement near support:a) Dead Load Shear:Total UDL per metre of bridge = 9720 Kg. Shear taken by outer girder = 3/8 x 9720 x 6.0 = 21,870 Kg. Shear taken by central girder = ¼ x 9720 x 6.0 = 14,580 Kg. Dead load shear due to weight of cross beam on outer girder = 1/4 of total shear = ¼ x ½ x 2090 = 260 Kg.
When is blocking/bracing within wood-frame walls required Shear panel edges. When using wood-frame shear walls, it is common to design the walls as blocked, resulting in significantly higher allowable shear capacities than unblocked shear walls. When designed as blocked, all shear panel edges must fasten to a common framing member; these common framing members are usually vertically-oriented studs and
WisDOT Bridge Manual Chapter 24 Steel Girder Structures January 2021 24-5 24.1 Introduction Steel girders are recommended due to depth of section considerations for short spanDesign/Construction Guide:Diaphragms and Shear Wallsand floors. A shear wall, however, is a vertical, cantilevered diaphragm. A diaphragm structure results when a series of such vertical and horizontal diaphragms are properly tied together to form a structural unit. (See Figure 1.) When diaphragms and shear walls are used in the lateral design of a building, the structural system is termed a
