Working with RF-/STEEL SIA
It is necessary to enter material, load and combination data in RFEM/RSTAB in compliance with the design concept specified by SIA 263.
The RFEM/RSTAB material library already contains relevant materials for SIA. Furthermore, RFEM/RSTAB automatically creates the corresponding load combinations according to SIA 260. However, you can also create all combinations manually in RFEM/RSTAB.
In the RF-/STEEL SIA add-on module, you can select members and sets of members as well as load cases, load combinations, and result combinations to be designed. You can adjust preset definitions of lateral intermediate supports and effective lengths in the subsequent input windows.
In the case of continuous members, it is possible to define individual support conditions and eccentricities for each intermediate node of single members. A special FEA tool determines critical loads and moments required for the stability analysis.

Results
For result evaluation reasons, there are clearly arranged result tables available. The first window shows the maximum design ratios including the corresponding design of each designed load case, load combination, or result combination.
The other result windows list all detailed results sorted by specific subjects in extendable tree menus. All intermediate results along a member can be displayed at any location. In this way, you can easily retrace how the module has performed the individual designs.
The complete module data is part of the RFEM/RSTAB printout report. You can select the report contents and the extent of the results specifically for the individual designs. Graphical result display of the governing design criteria in RFEM/RSTAB provides a quick overview of the design ratios of individual structural components.

Manual adjustment of the buckling curve according to EN 1993-1-1
The RF-/STEEL EC3 add-on module automatically transfers the buckling line to be used for the flexural buckling analysis for a cross-section from the cross-section properties. In particular for general cross -sections, but also for special cases, the assignment of the buckling line can be adjusted manually in the module input.
SHAPE-THIN | Cold-Formed Sections
SHAPE-THIN determines the effective cross-sections according to EN 1993-1-3 and EN 1993-1-5 for cold-formed sections. You can optionally check the geometric conditions for the applicability of the standard specified in EN 1993‑1‑3, Section 5.2.
The effects of local plate buckling are considered according to the method of reduced widths and the possible buckling of stiffeners (instability) is considered for stiffened sections according to EN 1993-1-3, Section 5.5.
As an option, you can perform an iterative calculation to optimize the effective cross-section.
You can display the effective cross-sections graphically.
