Creep coefficient

This value can be set in Concrete setting, see "Concrete settings" by using Advanced level or in 1D member data (advanced mode is ON), if is defined. Creep coefficient can be calculated automatically by using input ages of concrete and relative humidity (see annex B.1 in EN 1992-1-1), if the Type input of creep coefficient = Auto. If Type input of creep coefficient = User value., then creep coefficient can be input directly by the user.
