Serviceability limit state design for characteristic, frequent, or quasi-permanent design situation
Consideration of transverse welds
Variety of cross-sections provided; for example, I‑sections, C‑sections, rectangular hollow sections, square sections, angles with equal and unequal legs, flat steel, round bars
Clearly arranged result tables
Automatic cross-section optimization
Detailed result documentation with references to the design equations used and described in the standard
Filter and sorting options for results, including result lists by member, cross‑section, and x‑location, or by load cases, load combinations, and result combinations
Result window of member slenderness and governing internal forces
The first result window shows the maximum design ratios with the corresponding design for each designed load case and combination.
The other windows show all detailed results sorted by specific topics. It is possible to display all intermediate results of each location along the members. In this way, you can easily retrace how the module has performed the individual designs.
The complete module data are part of the RFEM/RSTAB printout report. You can select the report contents and extent specifically for the individual designs.
The data specified in RFEM/RSTAB concerning material, loads, and load combinations must comply with the design concept of the Eurocode. The RFEM/RSTAB material library already contains the relevant materials. Furthermore, RFEM/RSTAB allows for automatic creation of load and result combinations in accordance with the Eurocode. It is also possible to create the combinations manually.
In the RF-/ALUMINUM add-on module, you must first select the members and sets of members to be designed, as well as the load cases, load combinations, and result combinations. In the subsequent input windows, you can adjust preset definitions of lateral intermediate supports and effective lengths.
When using continuous members, you can define individual support conditions and eccentricities for each intermediate node of the single members. A special FEA tool determines the critical loads and moments required for the stability analysis.
