unsupported length
(OP)
Hi ,
Can any one let me know the unsupported length of top beam and LY of the transverse beam .
For some it may look simple but i have some confusion regarding that . Please see the attachment .

I want to know the Unsupported length of top flange and the Ly of main transverse beam .
Please see the attachment for clear understanding ,

In this case the top flange is is not connected so how top flange is restrained , hence i am confused.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
RE: unsupported length
Also in the case of a very long trolley beam, if the top flange of I trolley beam is supported by the bottom flange of supporting beams, can trolley beam be assumed restrained at support. I assume it restrained at support because trolley beam size becomes ridiculously large if I don't.
RE: unsupported length
I vote no for weak axis compression buckling but yes for lateral torsional buckling.
I assume so too. I guess that it would depend on the specific connection detail though. Can you have at least partial height stiffeners in the trolley beams at the supports without interfering with the trolley? Having the load applied at an elevation lower than the support is favorable although not necessarily sufficient.
