I cannot match the values that RC Pier generates for the column's moment magnification calculation for the Bd value (Ratio of Perm. Moment/Total Moment from AASHTO LRFD eqn 5.7.4.3-2). I have tried the minimum eccentricity from the AASHTO LFD code. I have tried the actual computed value of deflection. I have tried factored and not. Running out of time and patience. Anybody have any ideas?
