Check of provided reinforcement for SLS
First, the strain ratio εφ2 / εφ1 = 1.0 is assumed for the serviceability limit state. With it, the following values are determined:
mend,-z,φ1 = 38.49 kNm/m |
|
|
mend,-z,φ2 = 25.25 kNm/m |
Stiffening compression moment: |
mend,-z,strut = −22.94 kNm/m |
Direction of stiffening compression moment: |
φstrut,m,-z = 75.0° |
For these design moments, a required reinforcement of as,dim,-z,1 = 4.33 cm2/m in the first reinforcement direction and of as,dim,-z,2 = 3.04 cm2/m in the second reinforcement direction is determined at the top surface of the plate.
The required reinforcement for the internal forces of the serviceability limit state is smaller than the user-defined provided reinforcement. Hence, we can continue with the analysis.
