Design of bearing plates. Example 1: A simply supported plate girder bridge of 20 metres span carries a dead load of 50 KNm excluding selfweight of the girder and also a live load of 60 KNm per girder. Design the plate girder at the centre of the span considering the impact allowance as per IRC code.
Allan truss. Completed in November 1895, the Hampden Bridge in Wagga Wagga, New South Wales, Australia, the first of the Allan truss bridges with overhead bracing, was originally designed as a steel bridge but was constructed with timber to reduce cost. In his design, Allan used Australian ironbark Roof truss design. Steel roof truss design example is evident in the major structures built across the globe. Steel trusses are mainly used to build the strong base. They are being used for both buildings and bridges. Design of roof truss should follow the general layout that is prepared first.design example of steel truss bridge APPENDIX B Worked example Design of a truss node with gusset 79. Part 5: Detailed Design of Trusses 5 vi steel unit cost, etc. Trusses generally give an economic solution for spans over 20 or 25 m. An advantage of the truss design for roofs is that ducts and pipes that are
List of longest continuous truss bridge spans. For example, the list includes the Francis Scott Key Bridge which incorporates an arch shape into the design, but is continuous across multiple spans. The Key Bridge acts first as a continuous truss bridge and secondarily as an arch bridge. This list does not include cantilever bridges. design example of steel truss bridge This publication presents two worked examples of the design of composite. highway bridges using beam and slab construction.

AASHTO LRFD [Design Example for Steel Girder Superstructure Bridge 2003 Warren Truss Bridge Report The objective of this project was to design and construct the lightest bridge that can hold the greatest load, composed solely of Popsicle sticks and allpurpose glue. Truss bridges. A truss is a triangulated framework of individual elements or members which act primarily in tension or compression. Trusses have been used in a similar way to beams in composite decks (Oresund Approach Spans), as arches (Sydney Harbour Bridge), as cantilevers (Forth Rail Bridge) or as stiffening girders to suspension bridges (Forth Road Bridge).
