I’m trying to do a member design for a 200 PFC member on it’s side (i.e. the section has been rotated 90 degrees.) I’ll call this a 200PFC SIDEWAYS to avoid any confusion with a standard 200 PFC member.
The easiest way to model this is to select a library section and tick the “Section axis parallel to member y axis: XX.” That way the cross-section’s z axis is now oriented in the same direction as the web. So, for example a 200PFC SIDEWAYS will have a Zxx value of 3.27E+04 and a Zyy value of 1.91E+05. Simple enough....
However, when I run a Steel Member Check, Multiframe checks section values based on a standard 200 PFC member. I.e. Instead of analyzing in-plane loads against in-plane section properties, it just treats the applied (in-plane) loads as being out-of-plane. And then does an out-of-plane bending check. Which means Multiframe's just relying on a Section Bending design check and not considering a Member Bending design check.
How do I get the Steel Member Design/ Check to analyze my member properly? Do I have to create an entirely new section and add it to my library?
