Portal Frame:Eave member

[BECT]

Hello,

I am doing analysis and design of existing pre-engineered steel building based on current codes. The drawing shows 80X5E14 part no. for A eave member. Its like a C Shape ( with different top and bottom flange width) but from part no. I am not able to tell the size of the section like its flange width , depth of the section."14" is the gauge which I can tell. Does 5 represents flange width in inches , if that's right then what is "80"?

Regards

BEC

Sounds like a proprietary member. I think the only people who would know is the original manufacturer. It doesn't sound like any C-, Z-, or other type of member from the cold-formed steel manufacturers I know. Different top and bottom flange is an indicator of this; no standard section has that.

If you can't get in touch with the original manufacturer, you could just get on a scissor lift or something and measure it. Measure the flanges, flange leg, and depth with tape measure and the thickness with a caliper. The thickness will be the same throughout.

My best guess for what "80" means is that it's a series number, like it's in the 80 series of a certain type of channel and X5 is the fifth member of that series or maybe the flange width. 80 is probably not a metric measurement, because 14 gage is not metric. Just so you know, 5" is very unusual for a flange width. Most manufacturers don't have dies for anything past 3", and sometimes even 3" is a special order.

Thanks Milkshakelake ,

I will try my best to get hold of manufacturer or else will take measurements you suggested. Thanks once again for your suggestion.

Regards

FYI, it's unlikely the eave member is used for anything except to transfer axial loads down the building and into the bracing. They likely weren't designed for any bending. That's how the big PEMB manufacturers design them, considering it to be fully supported vertically by the wall panel that attaches to it.

It's most likely an 8" x 5" x 5" x 14 Ga eave strut. But you have to field verify.

The 80 is 8" depth perpendicular to the roof slope. The 5 is 5" bottom flange. The 14 is the gauge. I'm guessing that the top flange would be about 3".

Its not just the big PEMBs that use the wall panel as the vertical support of the wall.
