EC 2Ultimate strain 0.0035 (will reduce for 60 N/mm2 and above concrete strengthAll design based on characteristic cylinder strength fckC35/45 will refer as, C35 characteristic cylinder strength and C45 as characteristic cube strengthStatic Modulus Ecm , Dynamic modulus of elasticity Ed Ecm = (1.25Ed 19) kN/m2Steel specified characteristic strength, fyk = 500 N/mm2 Applied force = actionsCharacteristic action = mean action = 1.64 standard deviationsPartial Factor of Safety for Material = Design value of action = characteristic action x partial factor (f)Permanent action (Gk), Variable action (Qk)Favourable reduces the bending momentUnfavourable increase in bending moment
