Abstract: Design of many bridges is controlled by the fatigue requirements. Such control can be minimized if the classification from a non-redundant to redundant structure is selected. Such a classification may be selected, if secondary members are considered in the design. In order to illustrate such effects, a two girder system is examined, with and without bottom lateral bracing. One girder is considered in a cracked and uncracked flange condition. The preliminary results show the effect bracing has on the load redistribution.
