When you upgrade an RFEM 5 add-on module such as RF-STEEL AISC, you will now have access to all national and international standards in RFEM 6 including AISC 360, CSA S16, EC3, and many more. The separate standards under each design material are no longer sold as separate modules. If you currently have multiple modules for the separate standards (e.g. RF-STEEL AISC and RF-STEEL CSA), there will only be one upgrade fee for a material family. This will be a long-term cost savings.
The coefficient θ is calculated as follows:$$\mathrm\theta\;=\;\frac{\displaystyle{\mathrm P}_\mathrm{tot}\;\cdot\;{\mathrm d}_\mathrm r}{{\mathrm V}_\mathrm{tot}\;\cdot\;\mathrm h}\;$$
In the "Edit Section" dialog box, you can display the buckling shapes of the Finite Strip Method (FSM) as a 3D graphic.
In RFEM 6 and RSTAB 9, you have the option to enter "Visual Objects" as guide objects. You can import the file formats 3ds, stl, and obj.
These objects allow you to create a better reference to the dimensions.
Mia is accessible in the programs and prevents the hassle of following up by email or phone.
Using the "Damper" member type, you can define a damping coefficient, a spring constant, and a mass. This member type extends the possibilities within the Time History Analysis.
With regard to viscoelasticity, the "Damper" member type is similar to the Kelvin-Voigt model, which consists of the damping element and an elastic spring (both connected in parallel).
