Flange local buckling aisc
WebThe first local buckling parameter for flange is λpf which is=0.38*sqrt (Et/Fy) or sometimes written as =65/sqrt (Fy), this is derived if E=29000 /sqrt of Fy in KSI. We estimate the numerator as if multiplying 0.38*sqrt (2900),=0.38*170.29=64.711, which will be approximated as 65, λpf=65/sqrt (Fy) in ksi .
