Load Combinations

ENV 1991-1 Clause 9.4.5 allows the use of simplified combinations for building structures (Eq 9.13 and Eq 9.14). These combinations are implemented in RAM Frame. Combinations that include seismic forces are given by Eq 9.12. The Partial Safety Factors (γ Gsup , γ Ginf , γ I , and γ Q ) and Psi Factors (Ψ2) for those equations are specified in the RAM Manager Criteria - Eurocode Factors command. The special requirement that orthogonal seismic load cases be combined using 100% of one and 30% of the other is not implemented.
