Angel,
So far what you have written is correct so I am not sure exactly what your question is? If you are trying to calculate Mpr + Vp*(x+dc/2) here are the following definitions:
Mpr is as shown in equation (31).
Vp is as shown in Figure 33 but may vary depending if you have any point loads and/or uniform loads on the beam.
(x+dc/2) is the distance from the plastic hinge to the center of the column. This is the same as Sh and is defined separately for each connection in the Prequalification Data table under General.
I hope this helps,
Thomas Hunt, S.E.

Someone to clarify the spec:
"As a minimum Equation 93 of the 1997 AISC Seismic Provisions should be satisfied" (S M*pc/ S M*pb >1)
"In the application of Equation 93, the quantity Mc as defined in section 3.2.6 (Mc=Mpr + Vp*(x+dc/2)) of these Recommended Criteria should be substituted for the quantity M*pb "
The question is : The term M*pb in Equation 93 is now Mpr + Vp*(x+dc/2) ?
Thank you
