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
