E error in columns is due to Ndmax>0.5Ac.fck as far as I know. In ide, is this ndmax value the f1 value under the force-reinforcement areas heading? If not, which one? thanks for your answers
Re: ndmax error in column Axial load control in columns is done according to two different criteria. 1-Ndmax<0.5*Ac*Fck for vertical+earthquake loadings (TDY 2007 item 3.3.1.2) 2-Ndmax<0.9*Ac*Fcd for 1.4G+1.6Q loading (TS 500 made 7.4.1 Equation 7.7) Strength Reinforcement The Ni and Nj columns in the Fields Tab show the column axial load values.
