3.1.6: Design compression and tension strength

(1)P Design concrete compression strength is defined by formula (3.15)

where γcis 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)
