Combination for ultimate limit state
By selecting the corresponding General Data option, RFEM automatically creates a result combination that is used for the ultimate limit state designs. This result combination forms the envelope of the following load combinations:
- CO1: 1.35 ⋅ LC1 + 1.5 ⋅ LC2 + 1.5 ⋅ LC3
- CO2: 1.35 ⋅ LC1 + 1.5 ⋅ LC2
- CO3: 1.35 ⋅ LC1 + 1.5 ⋅ LC3
Combination for serviceability limit state
The combination factor ψ2,1 for the quasi-permanent action combination is applied with 0.6. As a superposition of load case results (RC) is excluded for nonlinear calculations, three load combinations with the following combination factors are used for the design in the serviceability limit state:
- CO4: LC1 + 0.6 ⋅ LC2 + 0.6 ⋅ LC3
- CO5: LC1 + 0.6 ⋅ LC2
- CO6: LC1 + 0.6 ⋅ LC3
