below the hook questions

[bnrg]

HI,
I have a few questions on ASME BTH-1-2005.

Para 3-2.3.1 Strong Axis Bending of Compact Sections
If the member is loaded in the strong axis (x-x) what does the comment 'loaded in the plane of the minor axis' mean? Isn't the minor axis the y-y?

Thanks,
Bob

I don't have ASME BTH-1-2005, but I think they are saying that the member is loaded in a manor that causes the member to bend about it's strong axis, not that the load is acting in that direction.

"loaded in the plane of the minor axis" means the the load is acting in the "y" axis causing the member to bend about the x-x axis (strong axis). So, yes, the y-y is the minor (weak) axis.
