Using the Timber Design add-on, timber column design is possible according to the 2018 NDS standard ASD method. Accurately calculating timber member compressive capacity and adjustment factors is important for safety considerations and design. The following article will verify the maximum critical buckling strength calculated by the Timber Design add-on using step-by-step analytical equations as per the NDS 2018 standard including the compressive adjustment factors, adjusted compressive design value, and final design ratio.
This article shows how to manage the input data for member and surface design configurations within the Stress-Strain Analysis add-on.
The stand-alone program RSECTION is at your disposal for determining section properties and performing stress analysis for thin-walled and massive cross-sections. The program can be connected to both RFEM and RSTAB so that sections from RSECTION are also available in the RFEM and RSTAB library. Likewise, internal forces from RFEM and RSTAB can be imported into RSECTION.
You can use the stand-alone program RSECTION to determine the section properties for any thin-walled and massive cross-sections, as well as to perform a stress analysis. The previous Knowledge Base article titled "Graphical/Tabular Creation of User-defined Cross-sections in RSECTION 1" discussed the basis of defining cross-sections in the program. This article, on the other hand, is a summary of how to determine the section properties and perform a stress analysis.
In the Stress-Strain Analysis add-on, you can use the option to specify sign-dependent limit stresses by stress component.
Get a better understanding of the stress distribution within member cross-sections by using clipping planes.
The deformation process of the global deformation components can be represented as a movement sequence.
The results of solid stresses can be displayed as colored 3D points in the finite elements.
In connection with the analytical SLS calculation, I get implausibly large values for the crack width and deformation in the RF‑CONCRETE add-on modules. What is the cause, and how can I fix the problem?
Is it possible to export the results from RF‑CONCRETE Surfaces to Excel? For example, I would need the steel stress of serviceability design.
Is it possible to adjust the initial values of the temperature courses entered for the fire resistance design? For example, I would like to adjust the initial value of the moisture content.
Is it possible in RF‑CONCRETE Surfaces to model a prefabricated slab or an element slab with different reinforcement layouts; for example, a reinforcement layer in a precast element and another reinforcement layer in the cast-in-place concrete extension?
How can I perform the fatigue design of reinforced concrete and prestressed concrete in RFEM 5? I have found a result combination for fatigue, but cannot find the design in the add-on modules.
Is it possible to perform stability analysis according to EN 1999‑1‑1 in RSECTION 1?
