Purpose: Used to define bolt holes in top flange at web splices.
--> Given in girder input
Number of holes in lateral direction in top flange at web splices for determinating amount of top flange removal for fatigue stresses. Useful if line of top flange holes differ from lines of bottom flange holes. TFNHOLES and BFNHOLES are used as an alternative to FNHOLES.
