Additional design assumptions for plain concrete: the coefficients αcc,pl and αct,pl
Eurocode 2 part 1-1: Design of concrete structures 12.3.1 (1)
Due to the less ductile properties of plain concrete the values for αcc,pl and αct,pl should be taken to be less than αcc and αct for reinforced concrete.
Recommendation
The recommended value for both αcc,pl and αct,pl is 0,8.
