RF-/STEEL EC3 | Design
When performing design of tension, compression, bending, and shear loading, the module compares design values of the maximum load capacity with the design values of actions.
If the components are subjected to both bending and compression, the program performs an interaction. RF-/STEEL EC3 provides options for determining interaction formulas by factors of the first method (Annex A) or the second method (Annex B).
The flexural buckling design, requires neither the slenderness nor the elastic critical buckling load of the governing buckling case. The module automatically determines all required factors for the design value of the bending load and the ideal elastic critical moment for each member on every x-location of the cross-section. If required, you only need to specify lateral intermediate supports of the individual members/sets of members, definable in one of the input windows.
If members are selected for the fire resistance design in RF-/STEEL EC3, there is another input window available where you can enter additional parameters such as types of coating or covers. Global settings covers required time of fire resistance, temperature curve, and other coefficients. The printout report lists all intermediate results and the final result of the fire resistance design. Furthermore, it is possible to print the temperature curve in the report.
