Question
How can I model a weld, for example as a fillet weld?Answer
To model a weld or fillet weld, the best way is to use a surface. In this case, the surface thickness is equal to the weld thickness.

Improved Cross-Section Optimization
When optimizing cross -sections in the add -on modules, you can also select any defined cross -section favorites lists - in addition to the cross -sections from the same cross -section row as the original cross -section.
SHAPE-THIN | Cold-Formed Sections
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.

- Which Dlubal Software programs are required to calculate membrane and tensile structures?
- How can I model a weld, for example as a fillet weld?
- How can I additionally model welds for the connection of two surfaces with a contact solid?
- I would like to analyze cable and tensile structures. Is it possible to use RFEM or RSTAB for this?
- Are the Dlubal Software programs suitable for the analysis and design of hydraulic steel structures?
- I would like to use surface releases to model a bolt connection, which can only absorb compressive stresses from the support. Unfortunately, I cannot do this because my model is always unstable. Is there a model as a template?
- 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?
- Can I quickly optimize all cross-sections in my model by using internal forces?
- What is the difference between the RF‑/STEEL and RF‑/STEEL EC3 add-on modules?
- I compare the flexural buckling design according to the equivalent member method and the internal forces according to the linear static analysis with the stress calculation according to the second-order analysis including imperfections. The differences are very large. What is the reason?
