Purpose: Used to specify wind loading as a local effect on a girder to determine box girder internal bracing forces prior to pouring of slab.
--> Given in girder input
An unfactored horizontal loading on the top flange due to wind (k/ft, kN/m). Used only to determine internal bracing forces in box girders under wind loading prior to the pouring of slab. Not applied in Girder System Projects as loading on the girder system, but only as a local effect on the girders for which it is given. Because aerodynamic effects can be different for wind blowing over a box girder when the slab has not yet been laid this data allows the user to apply a different wind load on the top flange for this loading case.
