Bracing for Lateral Torsional Buckling
Bracing for Lateral Torsional Buckling
(OP)
I need to brace the compression flange of a beam temporarily against lateral torsional buckling while a temporary load is added. I was wondering what the required force is to reist the buckling? I have heard that the rule of thumb is 2% of the flange force. Has anyone else heard this or know the exact answer?
Thanks
Thanks






RE: Bracing for Lateral Torsional Buckling
For a relative brace, the required brace strength is 0.008MrCd/ho , and the required brace stiffness is 4MrCd/(Lbho) either divided by phi or multiplied by omega depending on ASD/LRFD.

As far as I am aware, CISC makes no distinction between a "relative or nodal brace"
What is the difference between them?
