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.
