Error Message 1002 in RF‑STEEL AISC

After running the design in RF‑STEEL AISC, I receive error message 1002 – Invalid cross-section of type "Channel" according to F2. What does this error mean?


Answer:

Section F2 out of the AISC 360‑16 [1] states that doubly symmetric I-Shapes and Channels that are bent about their major axis must be compact sections in order to be designed. An example of this can be seen below.

Non-compact sections cannot be designed according to F2. Image 02 shows a non-designable section.
