Tension flange restraint
Tension flange restraint
(OP)
Has anyone any references (or thoughts about) the effect on the slenderness ratio if the tension flange only of a beam is restrained? This seems to be largely ignored in UK codes but is quite a common situation in lightweight structures. The only reference I have seen has been in the Canadian code for aluminium.






RE: Tension flange restraint
I do not think restraining the tension flange will increase neither the compressive strength of the beam element nor the flexural strength.
One of the best steel design text books is written by William "Bill" McGuire. This text is tremendous and covers the steel design from A to Z.
Good luck.

Please, can you give me more information about the book by McGuire (editorial, year...).
Thank you.

In my humble opinion, this book is the best and most comprehensive steel design book out there. It is full of theories and examples. I am not a big fan of theory only and a bunch of integrals and differentiations and no practical aspects.
Good luck.
RE: Tension flange restraint
The restraint of the tension flange provides some restraint to the compression flange through the bending strength of the web. This approach is commonly used in light-gage shapes as channels and Zees that support siding or roofing subject to reversal of wind loads.
The book "Cold-Formed Structures" by Wei-Wen Yu shows a method to calculate the equivalent restraint to the compression flange of a light-gage section. I think the same method could be applied to structural steel shapes.

dlew, I think the your reference is exactly what I'm looking for.
Thanks all
