Less generated load combinations by defining the leading variable actions
To carry out a structural analysis for a structural system according to the current standards, it is necessary not only to deal with actions and resistances of structural components but also with the combinations of the actions.
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.

- Is it possible to set user-defined values when viewing solid stress results?
- How can I create a curved or arched section?
- I would like to calculate and design "temporary structures." What do I need for this?
- I design a cross-section created in the SHAPE‑THIN program by using the RF‑STEEL EC3 add-on module, but the program shows the error message "ER006 Invalid type of c/t-part for cross-section of type General." What can I do?
- I would expect the results from my load combination (CO) set to a linear analysis to equal the summation of the results from my load cases (LC) also set to a linear analysis. Why do the results not match?
- A rigid member should only be able to absorb tensile forces or only compressive forces. What are the options for considering these nonlinearities in the calculation?
- Which Dlubal Software programs are required to calculate membrane and tensile structures?
- In a 3D model consisting of three identical floors, I applied a unit load of 1 kN/m² to the top slab to determine the spring stiffness of the supports for 2D modeling of the slabs from normal forces and deformations of the columns. Despite the deactivation of the self-weight of the structure, there is a redistribution of the column normal forces by storey. Is it possible to deactivate this effect?
- How can I consider a hole in the web that is only near the support? The parameterization can only be applied to the centrally arranged holes with the same distance.
- How can I additionally model welds for the connection of two surfaces with a contact solid?
