ACI 318-19 : Minimum Flexural Strength of Columns
TSC 2018 : Conditions for Columns to be Stronger than Beams (Strong columns)
...
The columns of special moment frames are considered as part of the seismic-force resisting system. The subject of this title is to reduce the possibility of yielding in columns of special moment frames. Columns not stronger than beams increased likelihood of inelastic action. The worst possible case is when all columns in a given story have flexural yielding at both ends. In this case, it creates a column failure mechanism to cause collapse. In order to avoid this situation, the minimum flexural strength of colums control given in Codes should be satisfy.
