Basically,
Bearing N has to be looked in 2 cases:
1)The bearing of column (load) on beam - N is based on the thickness of column (ex. if W150X30 column, then N= 152, or if the column is supported by a plate on the beam, let's say a 200x200mm, then N=200)
2)The second case N at reactions...
For Web yielding/crippling, the length of bearing N is suppose to considered where the load is applied, what is this variable exactly, where is it located?
Also to figure out whether the concentrated load is applied Interior or at Ends, the code refers to the distance from end of beam greater...
