Can anybody give me guidence (or suggest any book) for design of lateral (wind) bracing of bridge girders.How we can incorporate/add wind load in to the load calculations during construction i.e before placement of concrete deck?
You can design the bracing system as though it were a truss. I assume you checked AASHTO to see if bracing is needed.
If this is LRFD you have to perform the calculation for bracing the compression flange during construction. If you’re using the Standard Specs no check for construction conditions is required. However, there are methods you could use. For instance, check the girder about the weak axis assuming the diaphragms act as a support.
The old old US Steel bridge design manuals had an example.
