Annotation:
Design compression and tension strength
(1)P Design concrete compression strength is defined by formula (3.15)
where γc is partial factor of conctrete, see 2.4.2.4;
αcc coefficient taking account of long term effects on the compressive strength
remark - αcc is defined by national annex, it maybe 0,8 - 1,0, recommended value is 1 (NP12)
(2)P Design concrete tension strenght is defined by formula (3.16)
where γc is partial factor of conctrete, see 2.4.2.4;
αct coefficient taking account of long term effects on the tensile strength
remark - value αct is defined by national annex, recommended value is 1 (NP13)
