WebThis has changed in the 2010 AISC Specification. The stem local buckling strength is no longer included in the lateral-torsional buckling equations. Tee stem width-to-thickness limits were added as Case 14 in Table B4.1 and a new Section F9.4 was added to specifically address the stem local buckling strength.

Webproved to be far too conservative. Thus, the stem local buckling provisions for tees have been completely revised. They now take on a format similar to that shown in Figure 1 with a comparison between the 2010 and 2016 provisions shown in Figure 2. Flange local buckling of tees remains unchanged for 2016 and follows the pattern shown in Figure 1. WebFor built-up I-sections, 21 in Fig. 2 is adopted from AISC 1999.

WebThe objectives of this paper are to (1) provide analytical expressions for the elastic cross-section local buckling stresses, including element interaction, of hot-rolled steel structural shapes, and (2) compare these local buckling results to the assumptions inherent in the local slenderness limits of the US AISC structural steel specification. The cross-section … WebAn experimental and analytical research program was recently completed that examined in detail the parameters affecting the strength and ductility of high-performance steel (HPS) flexural members.HPS is a term used to describe a new class of steels being produced under strictly controlled conditions that have high strength, usually greater than 448 MPa … Weblimit state, i.e. lateral torsional buckling (LTB) and flange local buckling (FLB) are prevented by the selection of the flange width-to-thickness ratio and sufficient spacing of lateral braces.
