Flange local buckling aisc
Webexpressions for carbon steel in AISC 360 for yielding and flange local buckling were shown to apply to stainless steel providing the stainless steel values of p and λrλ are used (as given in Table 3-1 and 3-2 of the guide). For rectangular HSS, the AISC 360 expressions for flange and web local buck-ling were not given in terms of p and λλ r, WebFlange local bending (J10.1) is based on a yield line analysis, which assumes a flange on each side of the web. It might make sense to assume only half the yield lines can be …

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 .
