Design compressive action for the critical load combination, Nd (Table 2.8, equation (c) using the unfavourable condition)

5. Modification factors

Factor for medium-duration loading and service class 2, £mod.med (Table 2.4 (EC5, Table 3.1))

System strength factor, ksys - not relevant

6. Compression strength of column

The critical design load case at the ULS will be due to the combination of permanent and unfavourable medium-duration variable action:

Design compression stress, ac.0.d oc.0.d = (equation (8.7))

Design compression /c 0 d = strength, /c.o.d

Atot kmod.med • ksys • fc.O.k ac0d — 4.94 N/mm2
