The support conditions of a beam subjected to bending are essential for its resistance to lateral-torsional buckling. If, for example, a single-span beam is held laterally in the middle of the span, the deflection of the compressed flange can be prevented, and a two-wave eigenmode can be enforced. The critical lateral-torsional buckling moment is increased significantly by this additional measure. In the add-on modules for member design, different types of lateral supports on a member can be defined using the "Intermediate supports" input window.
In RF-/FOUNDATION Pro, you can also consider the concrete cover for the foundation according to EN 1992-1-1.
The Eurocode for DIN EN 1991‑1‑4:2010‑12 describes wind loads acting on structural systems.
For automatic load case combination in RFEM and RSTAB, you have to enter the possible interaction of load cases. In addition to the simultaneous or alternative occurrence of all load cases of an action, an option for different combination conditions is possible.
In RF-/FOUNDATION Pro, a graphical display of the result details is available. To see them, go to Window 2.2 Governing Design Criteria after the calculation. In the interactive graphic of this window, individual design-relevant values can be displayed for each design performed.
In RFEM and RSTAB, different graphical representations of the foundation dimensions are available.
For foundation design, it is necessary to define the relevant loads for the respective design situations (STR, GEO, UPL, EQU).
In RF‑/FOUNDATION Pro, you now have the option to design a foundation at one or several nodes of the model.
When calculating foundations according to EC 7 or EC 2, different foundation types or sizes are usually used in one object. However, boundary conditions like the soil parameters, the materials for foundations, concrete covers, and the load combinations selected for design remain the same for all foundations, as a rule.
In RFEM and RSTAB, snow drift is considered according to 5.3.4(3) of DIN EN 1991‑1‑3 for saw-tooth roofs.
