Abstract:This paper uses a parametric numerical study to assess the Lateral-torsional buckling (LTB) performance of several semi-compact beams: S1, S2, and S3. The carrying capacity of these beams, predominantly loaded in bending, is approached by elastic and inelastic buckling analyses. A series of parameters that are believed to influence the resistance to LTB of class 3 beams to (EC3) steel I-beams, namely boundary conditions, flange thickness, and load application level, are investigated. An eigenvalue analysis tha… Show more
