Braced Frame Gusset Plates Design

[2meterman]

I have a project where I need to design a steel braced frame to resist wind loads.

I have the columns, braces and welds figured out but have not been able to find a good reference for determining the thickness of the Gusset Plates in the braced frame.

Can someone suggest a good reference manual for determining the gusset plate thicknesses?

Thanks!

You can find some good examples on the companion CD to AISC's Steel Manual 13th edition. These have complete connection checks. The manual itself has really nice coverage of the Uniform Force Method, which allows you to calculate forces on each interface (gusset-beam or gusset-column). See Chapter 13 for that discussion and illustrations.

I don't know much about statistics, but I do know that if something has a 50-50 chance of going wrong, 9 times out of 10 it will.

Yep, AISC Uniform Force Method.

Do a google search for "whitmore section" you will find some good information regarding a commonly held gusset plate design assumption.

I believe the Whitmore is covered in the Uniform Force method

If you can find it, the 1992 Connections manual has excellent examples of the Uniform Force Method.
