What is Equivalent Imperfections For The Out-Of-Plane Stability Design of Steel Beams by Second-Order Inelastic Analysis about?
The document discusses the development of equivalent imperfections for the out-of-plane stability design of steel beams using second-order inelastic analysis (GMNIA). It highlights the inadequacy of current design specifications for lateral-torsional buckling (LTB) in beams and proposes two new imperfection amplitudes, e0,mod and e0,bow, calibrated against finite element simulations. The study demonstrates that using these proposed imperfections results in more accurate predictions of member resistance whil
