Open the window:
Data->Loadcases
And select the option Use combined load cases.
Rambshell will give a different result for every combined loadcase. To change the name of one load case, double click over it and write the new name. To add a new combined loadcase, press right button mouse over it and select insert after.
The field ELU is not used for the analysis. It will be used later, when dimensioning the steel, to decide if this combined loadcase is used to calculate the section against collapse or against service states, like fisuration. Enter the coefficients that will amplify the loads. The combined loadcases used for this problem are:
Combined loadcase | Amplification factor for Peso propio | Amplification factor for Sobrecarga | Will be used for section collapse checking |
Peso propio+sobrecarga servicio | 1.0 | 1.0 | NO |
Peso propio+sobrecarga último | 1.5 | 1.6 | YES |
