South African Standards (SANS)
Standards and codes are important. Where do you plan your project and what do you have to pay attention to? When it comes to international standards, the Dlubal programs are reliable companions for customers from all over the world. You will find numerous standards integrated in RFEM and RSTAB, whereby the corresponding add-ons allow you to design steel, reinforced concrete, and timber structures. Here you will find an overview of the standards available in the programs for the respective countries.

RFEM 6&nbs;/ RSTAB 9 makes your work a lot easier. If you wish, you will receive the automatic load and result combinations according to the South African standard SANS 10160‑1.
Structural FEA Software RFEM 6 Structural Frame & Truss Analysis Software RSTAB 9In the RF-/STEEL SANS add-on module for RFEM 5 / RSTAB 8, you will find numerous useful options. For example, the program delivers the ultimate and serviceability limit state design checks for members according to the South African standard SANS 10162‑1 with just a few clicks.
RF-/STEEL SANS Add-on Module for RFEM 5/RSTAB 8The RF‑/TIMBER SANS add-on module for RFEM 5 / RSTAB 8 allows you to perform the ultimate and serviceability limit state design as well as fire resistance design of members according to the South African standards for timber structures SANS 10163‑1 and SANS 10163‑2.
RF-TIMBER SANS Add-on Module for RFEM 5The RF‑/DYNAM Pro - Natural Vibrations add-on module for RFEM 5 / RSTAB 8 determines natural frequencies and mode shapes.
The RF-/DYNAM Pro - Equivalent Loads module extension for RFEM 5 / RSTAB 8 generates equivalent seismic loads according to the multimodal response spectrum analysis. Among others, the South African standard SANS 10160‑4 is implemented.
RF-/DYNAM Pro - Natural Vibrations Add-on Module for RFEM 5/RSTAB 8 RF-/DYNAM Pro - Equivalent Loads Add-on Module for RFEM 5/RSTAB 8In the "Edit Section" dialog box, you can display the buckling shapes of the Finite Strip Method (FSM) as a 3D graphic.
- Design of five types of seismic force-resisting systems (SFRS) includes Special Moment Frame (SMF), Intermediate Moment Frame (IMF), Ordinary Moment Frame (OMF), Ordinary Concentrically Braced Frame (OCBF), and Special Concentrically Braced Frame (SCBF)
- Ductility check of the width-to thickness ratios for webs and flanges
- Calculation of the required strength and stiffness for stability bracing of beams
- Calculation of the maximum spacing for stability bracing of beams
- Calculation of the required strength at hinge locations for stability bracing of beams
- Calculation of the column required strength with the option to neglect all bending moments, shear, and torsion for overstrength limit state
- Design check of column and brace slenderness ratios
The seismic design result is categorized into two sections: member requirements and connection requirements.
The "Seismic Requirements" include the Required Flexural Strength and the Required Shear Strength of the beam-to-column connection for moment frames. They are listed in the ‘Moment Frame Connection by Member’ tab. For braced frames, the Required Connection Tensile Strength and the Required Connection Compressive Strength of the brace are listed in the ‘Brace Connection by Member’ tab.
The program provides the performed design checks in tables. The design check details clearly display the formulas and references to the standard.
In the Concrete Design provides an option to perform seismic design according to AISC 341-16 for steel members.
Five SFRS types (Seismic Force-Resisting Systems) are available for this.
