If SLS loads have been defined, the software takes the quasi-permanent load (Mser,qp,d, Eq. 2.1.4b) as default value. If not, the default value is adjusted to 70% of the design load at ultimate (0.7xMs,d, Eq 2.1.4a).
The user can directly input the value by using the third option, which allows entry of a specific value based on an exact calculation of the fire load combination, according to the local regulations.
After this, the information is shown in the graphical area, together with a message that indicates if the CFRP strengthening needs protection in case of fire, according to the expected load and the strength of the unreinforced element (Fig. 3-25 and 3-26).
