Topic: Coef. of cracked wall stiffness

Coef. of cracked wall stiffness  =                                  This    parameter     defines    the   reduction     of  initial wall stiffness due to the tensile cracking. The recommended value is 0.50 (see EN 1998-1, Section 4.3.1 (7)).

How is this parameter taken into account during the calculation. Is the cross section stiffness automaticly reduced to 1/2 in the begining or is this factor included somehow else?

Re: Coef. of cracked wall stiffness

Yes, you are right.
The cross section is stiffness automaticly reduced to 1/2 in the begining.
