Placing Node Between Two Points
Tips & Tricks
If you wanted to determine the center of a rectangle, it was previously necessary to construct a line from one corner point to the opposite one. By dividing this line, you obtain the centroid. In RFEM 5 and RSTAB 8, you now have the possibility to create a node between two points. Thus, it is sufficient to select the corner points, and then you can determine the distance in absolute or relative values.

In EN 1993-1-1, the General Method was introduced as a design format for stability designs, which can be used for planar systems with any boundary conditions and variable structural height.
The model is constructed by means of parameters for geometry and loads and regenerates when the parameters are changed.

SHAPE-THIN determines the effective cross-sections according to EN 1993-1-3 and EN 1993-1-5 for cold-formed sections. You can optionally check the geometric conditions for the applicability of the standard specified in EN 1993‑1‑3, Section 5.2.
The effects of local plate buckling are considered according to the method of reduced widths and the possible buckling of stiffeners (instability) is considered for stiffened sections according to EN 1993-1-3, Section 5.5.
As an option, you can perform an iterative calculation to optimize the effective cross-section.
You can display the effective cross-sections graphically.

- In connection with the calculation according to the large deformation analysis, I get significantly smaller deformations than for the calculation according to the linear static or second-order analysis. How is this possible?
- How is it possible to consider the real cross-section geometry of member elements in RWIND Simulation?
- My aim is to mesh a circular hole plate in a mapped way. Is such a meshing possible in RFEM?
- Why do I get large differences for the design of a longitudinally stiffened buckling panel in comparison with the German and Austrian National Annex?
- How can I perform the stability analysis in RF‑/STEEL EC3 for a flat bar supported on edges, such as 100/5? Although the cross-section is rotated by 90° in RFEM/RSTAB, it is displayed as lying flat in RF‑/STEEL EC3.
