Aircraft structures are made of thin-walled as it provides higher stiffness to weight ratio compared solid sections, but is prone buckling due its low and slenderness the individual element. One types that can impact integrity a beam lateral torsional which caused by simultaneous bending twisting cross-sections happens before beam's material strength reached. Therefore, design such structure sh...

This article investigates the flexural response of cantilevered top chord extensions open web steel joists used in building structures. Currently, no design guidance is available to assess bending capacity these members with consideration local and lateral-torsional buckling failure modes. The objective study was develop a numerical finite element model capable predicting behaviour 13 joist tes...
