Steel Design for RFEM 6 / RSTAB 9

Features

• A wide range of available sections, such as rolled I-sections; channel sections; T-sections; angles; rectangular and circular hollow sections; round bars; symmetrical and asymmetrical, parametric I-, T-, and angle sections; built-up cross-sections (suitability for design depends on the selected standard)
• Design of general RSECTION cross-sections (depending on the design formats available in the respective standard), for example, equivalent stress design
• Design of tapered members (design method depending on the standard)
• Adjustment of the essential design factors and standard parameters is possible
• Flexibility due to detailed setting options for basis and extent of calculations
• Fast and clear results output for an immediate overview of the distribution of results after the design
• Detailed output of design results and essential formulas (comprehensible and verifiable result path)
• Numerical results clearly arranged in tables and graphical display of the results in the model
• Integration of the output into the RFEM/RSTAB printout report

Cross-Section Resistance

• Design of tension, compression, bending, shear, torsion, and combined internal forces
• Tension design with consideration of a reduced section area (for example, hole weakening)
• Automatic classification of cross-sections to check local buckling
• Internal forces from the calculation with Torsional Warping (7 DOF) are taken into account by means of the equivalent stress check (currently not for the design standards AISC 360‑16 and GB 50017).
• Design of cross-sections of Class 4 with effective cross-section properties according to EN 1993‑1‑5 as well as cold-formed sections according to EN 1993-1-3 (licenses for RSECTION and Effective Sections are required for the RSECTION cross-sections)
• Shear buckling check according to EN 1993‑1‑5 with consideration of transverse stiffeners
• Design of stainless steel components according to EN 1993‑1‑4

Stability Analysis

• Stability analyses for flexural buckling, torsional buckling, and flexural-torsional buckling under compression
  • Import of the effective lengths from the calculation using the Structure Stability add-on
• Graphical input and check of the defined nodal supports and effective lengths for a stability analysis
• Lateral-torsional buckling analysis of the structural components subjected to moment loading
  • Depending on the standard, a choice between user-defined input of Mcr, analytical method from the standard, and use of internal eigenvalue solver
  • Consideration of a shear panel and a rotational restraint when using the eigenvalue solver
  • Graphical display of a mode shape if the eigenvalue solver was used
• Stability analysis of structural components with the combined compression and bending stress, depending on the design standard
• Comprehensible calculation of all necessary coefficients, such as the factors for considering moment distribution or interaction factors
• Alternative consideration of all effects for the stability analysis when determining internal forces in RFEM/RSTAB (second-order analysis, imperfections, stiffness reduction, possibly in combination with the Torsional Warping (7 DOF) add-on)

Input

You enter the structural system and calculate the internal forces in the programs RFEM and RSTAB. You have full access to the extensive material and cross-section libraries. Did you know? You can also use theRSECTION program to create general cross-sections.

You find Steel Design fully integrated in the main programs. They automatically take into account the structure and the available calculation results. You can assign further entries for the aluminum design, such as effective lengths, cross-section reductions, or design parameters, to the objects to be designed. At many places of the program, you can easily select the elements graphically using the [Select] function.
