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. Figure 2 shows a non-designable section.
