Question

I get a message saying that the General Method is only allowed for I-sections, even though I do want to design an I-section. Why?


Answer:

In order to recognize a cross-section as an I-section in RF‑/STEEL EC3, it is necessary to define a cross-section of the I-section type. This is the case with rolled and welded I-sections from the cross-section library, but not for built-up or modified cross-sections. Therefore, an ICM section (a modified cross-section) can no longer be automatically recognized as an I-section, for example.


The easiest way to design a cross-section with the General Method is to change the settings. You can also activate the design for other cross-sections using the "Enable also for non I-sections" option.
