I am designing a concrete frame in Zone 3. UBC (1994 - 1631.1 and 1997 - 1633) states that if the seismic axial load in the column is less than 20% of the column capacity then simultaneous orthogonal effects do not have to be checked. PCA Design Notes for ACI 318-95 example on page 31-60 show that the column capacity is based on axial load only. Is this the correct way to check it? You take the column capacity with no moment (eccentricity = zero) and if the seismic load is less than 20% of this you do not have to check simultaneous seismic forces? How does column slenderness affect this check? Rich __________________________________________________ Richard Lewis, P.E.
