Design tensile strength of concrete: the value of αct
Eurocode 2 part 1-1: Design of concrete structures 3.1.6 (2)P
The value of the design tensile strength is defined as
|fctd = αct fctk,0,05 / γC||(3.16)|
- is the partial safety factor for concrete, (see § 188.8.131.52 (1), § 184.108.40.206 (2), and § 220.127.116.11 (3))
- is the coefficient taking account of long term effects on the tensile strength and of unfavourable effects, resulting from the way the load is applied.
The recommended value of αct for the calculation of the design tensile strength of concrete is 1,0.
