    Cold Form yield stress

    I understood that. So that means. I have to estimate that? Until I meet local buckling? Is that it? Are there any property tables precalculate aside from 33 and 50ksi fy? Or any free software that calculates effective properties?

    Cold Form yield stress

    how about the compressive force 37.25? Did the author just assume that how do I calculate that? Can't i use its FY which was 55 ksi?

    Cold Form yield stress

    Hi, I wanna ask if cold form is limited only to gr.33 and gr.55? Because upon seeing the AISI Manual Cold-Formed Steel Design 2002 Edition. Especially how they calculate the effective sections. Was based only to gr.33 and gr.55. Is that true? And in addition, I just wanna ask why they used...

    Distortional buckling of C channels without lips

    Hi, Do C-Channels without lips exhibit distortional buckling? And if does what's the formula to use? And how do I use the AISI (Eq. C3.1.4-6) formula to non-lipped channels? Is it applicable? kind regards, Tramyer
