Add-on Modules RF-STEEL EC3 STEEL EC3 ALUMINUM RF-ALUMINUM

Calculating a result combination in STEEL EC3 or Aluminium takes a very long time. What might be the cause and how can I improve the performance?

Answer

Cross-sections of the type "General" might cause this long-lasting analysis in STEEL EC3 and Aluminium.

You find them in Table 1.3 Cross-Sections. For these cross-sections, it is necessary to calculate the stresses for the cross-section classification with SHAPE-THIN in the background. The result combination (RC) for the design may contain many load combinations (CO). This could lead to the fact that the SHAPE-THIN analysis will be performed very often and might take a very long time. However, there is a workaround. With the option displayed in the second figure, the enveloping internal forces of the RC are used, and each CO included in the RC cannot be calculated. This may be more conservative, however, it is faster because not every CO requires a SHAPE-THIN analysis, only the envelope.
