Purpose: Used to define intermediate transverse web stiffeners.
--> Given in girder input
The gap between the tension flange and the edge of transverse stiffeners (inches or mm) to reduce fatigue stresses. In LFD and ASD, unless connection plates are specified to extend to both flanges (see FULL DEPTH CONNECTION PLATES ), the transverse stiffeners that coincide with bracing locations, i.e. are connection plates, also will have this gap. Note: STFGAP does not apply to connection plates in LRFD, in which case STFGAPCP must be used for connection plates if the user wants to provide a cutoff for welding, such as in case a bolted connection connects the connection plate to the tension flange.
