Column Lateral Bracing Design

Column Lateral Bracing Design

Column Lateral Bracing Design

(OP)
I am checking a steel column inside a 2x4 wall that requires lateral bracing at 8 feet. The wall is 15' high. How do I determine what load the bracing should be designed for if I know the column and the vertical load?

RE: Column Lateral Bracing Design

typically it is a percentage of the axial load. I believe the theory works out to be about 2-3% of the axial load is needed. i don;t have my stability book to check that number. i usually design for 10% of the axial to be safe, as long as it is not rediculous of course

RE: Column Lateral Bracing Design

There is a more exact method, developed by Yura I think, that checks both stiffness and strength of the brace.  Salmon and Johnson describe the method in "Steel Structures--Design and Behavior."  But they also conclude that the 2% rule works pretty well.  I would design for 2% of the axial force in the column.

Appendix 6 of the new 2004 AISC specification addresses stability bracing for columns and beams.
