When choosing the “Greek ELOT-EN NA method” the minimum diameter of the transverse reinforcement in the column is given in the National Annex:

ϕ_cl,tmax = min(10 mm; 0.25 ∙ ϕ_l) for ϕ_l ≤ 28 mm

ϕ_cl,tmax = min(12 mm; 0.25 ∙ ϕ_l) for ϕ_l > 28 mm

where:

ϕ_l is minimum diameter of the longitudinal bars
