By enabling this option, the software verifies the performance of the reinforced concrete member under quasi-permanent and characteristic combination of loads:
As shown in 2.1.3, the strains and stresses developed by the compressed concrete and tensile steel must be limited under certain values, to avoid excessive creep and/or cracking.
The user must input the expected SLS design moments for the strengthened member:
The characteristic load combination value must equal or exceed the expected quasi-permanent load combination value, but cannot exceed the value requested for ULS.
