Re: Allowable Bending stress for WT's

[Subject Prev][Subject Next][Thread Prev][Thread Next]
You're right, tee bending is not covered explicitly or even well suited 
to be in a psuedo-elastic method such as allowable stress 
design...primarily because lateral torsional buckling or local buckling 
usually controls. You can find guidance however, in AISC's Load and 
Resistance Factor Design (LRFD) Specification for Structural Steel 
Buildings, both in Chapter F and in Appendix F.
