Buckling Restraint examples
Buckling Restraint examples
(OP)
Hi,
I'm after some information about buckling restraints for beams. My understanding is that it reduces the effective length.
After pictures which demonstrate what a XX column restraint and YY column restraint are in real life.
I use Microstran (but assume its same for other structural code checkers)
Thanks,
Joe Banger

Can some one suggest a more appropriate forum for me to post information. Would have thought that Structural Engineering was apt.

But this is taught in Steel Design 1 (I'm assuming you're designing steel). If you don't know this, I question what you're designing.

A member restraint at a point along the length of a member is anything which prevents the member from deflecting at that point, i.e. a bracing member. So if a beam is 20' long and I am concerned about lateral torsional buckling (LTB), I could laterally brace the compression flange at midspan so that the unbraced length is reduced to 10'. In that way, the beam can resist much larger moments without lateral torsional buckling.
In the case of a column, the entire cross section may be in compression, so bracing at discrete points would increase resistance to axial buckling. XX and YY refer to the major and minor axis of the section. Sometimes the minor axis is braced at closer intervals than the major axis.
I have never used Microstran, but the attached provides some further information which you may find useful:

No thanks to JedClampett for your hubris and arrogance - people like you make forums an intimidating place for newcomers like me.
My application is a temporary structure (aid work) in a cyclonic jungle area. not a critical structure as they rebuild them after a TC or storm.
