Consideration of the Effects of the Second-Order Theory

When you use the results of such load combinations for design in RF‑FOUNDATION Pro, the effect of the second‑order analysis is missing in the foundation design. The reason is that the RF‑FOUNDATION Pro module uses the support reactions of individual LCs for the design.

In order to consider the support moments according to the second‑order analysis anyway, RF‑FOUNDATION Pro provides the option to affect the support moments according to the linear static analysis by a user‑defined factor. You can enter these increment factors separately for both design directions in the "Details" dialog box of the RF‑FOUNDATION Pro add‑on module. Please note that this entry applies to the entire design case.

If there is a moment applied with a certain factor, it will be recorded in the design details and in the result tables of the printout report by entering the multiplication factor.
