A fillet weld is the most common weld type in steel building construction. According to EN 1993‑1‑8, 22.214.171.124 (1), fillet welds may be used for connecting structural parts where the fusion faces form an angle between 60° and 120°.
The product range of Dlubal Software contains various modules for design of steel and timber connections. The RF‑/JOINTS Steel - Column Base add‑on module allows you to analyse footings of hinged or restrained steel column bases.
The add‑on modules RF‑PIPING and RF‑PIPING Design allow you to design piping systems according to EN 13480‑3, among other standards. In this case, the determination of pipe stresses is based on the formulas of Section 12.3 Flexibility analysis.

Wind is the only climatic load acting on every single type of structure in the entire world, different from other loads like snow, for example. The wind size depends on the geographical location of the structure.

Watch the new video and learn how to determine buckling shapes and imperfections using the add‑on modules RF‑STABILITY and RF‑IMP.
According to EN 1993‑1‑1, it is necessary to use the equivalent geometric imperfections with values that reflect the possible effects of all types of imperfections. EN 1993‑1‑1, Section 5.3, specifies basic imperfections for global analysis of frames as well as member imperfections.
In RFEM, structures can be modelled and analysed in a spatial environment. The permanent 3D visualization helps to better understand complex models and to represent the force flux. However, it is also possible to switch from a spatial mode to a planar sheet mode in the documentation of a calculation.
In the case of a post‑critical failure, a substantial change in the geometry of a structure occurs. After reaching the instability of the equilibrium, a stable, strong position is reached again. The post‑critical analysis requires an experimental approach. It is necessary to manually load the structure in increments step by step.
