Working with RF-/STEEL BS
It is necessary to enter material, load and combination data in RFEM/RSTAB in compliance with the design concept specified by BS 5950 (or Eurocode). The RFEM/RSTAB material library already contains relevant materials for BS 5950.
RFEM/RSTAB automatically creates the corresponding load combinations according to BS 5950 (or Eurocode). However, you can also create all combinations manually in RFEM/RSTAB. The RF-/STEEL BS add-on module requires members and sets of members as well as load cases, load combinations, and result combinations to be designed.
In the next input windows, you can adjust preset definitions of lateral intermediate supports and effective lengths. 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
The first result 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 subject 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.
Complete module data is part of the RFEM/RSTAB printout report. You can select the report contents and extent specifically for the individual designs.

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.
