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...
Hello,
I am designing a concrete foundation for a steel pre-engineered building.
The spread footings at each column are located approximately 5 feet below finished grade.

When I do structural design for residences I often find that a steel moment frame is necessary in a large window wall.
Normally I talk with the owner to discuss ways of reducing the windows so we can get wood framed shear walls to work or use a manufactured steel shear wall.
However, I would...
I'm designing a basement with an adjacent garage so that the wall is completely backfilled and also has a potential wheel load as a surcharge on the basement wall.
My calculations show that the reaction at the top of the wall is 550 lbs horizontal. I've looked through my NDS books and all the...

The loading of the bracket is 8,500 lbs with...
