Design guide 16 and clumn flage check.
(OP)
if i am designing an end plate following the procedure of design guide 16, do i have to check the cloumn flange for flexural yeilding.??
and if i do how could i calculate Mcf when there is no such formulas in desgn gude 16 for the clumn, and there is all the cormulas in deisgn guide 4 are fo r extended end plates? ? ?

That being said, it is probably unlikely that column flange bending is going to control. Column flanges are usually a good bit thicker than the end plates, right?

Some End Plate connections do not have column yield line formulas specifically listed in the design guides.
Note:
•The column yield lines for the 8 bolt (unstiffened) connection is not given in the design guides. But, can be found in section 4.4.5.5 and Figure 4-15 of Emmett Sumner's PhD thesis, Unified Design of Extended End-Plate Moment Connections Subject to Cyclic Loading.
•The 2 bolt flush end plate connections will have the same yield lines as the Yp values in table 3-2 of AISC Design Guide 16. The only difference is that bp (plate width) is replaced with bcf (column flange width), tp (plate thickness) with tcf(column flange thickness). In addition "s" is used instead of Pf for the distance to the top yield line unless a transverse column stiffener is present in which case the distance between this stiffener and the top row of bolts is used in place of Pf.
• The 4 bolt flush end plate connections will have the same yield lines as the Yp values in table 3-3 of AISC Design Guide 16. The same differences mentioned in the bullet point above for the 2 bolt flush connection also apply to the 4 bolt flush connections.
