INELASTIC LATERAL - TORSIONAL BUCKLING; OF RESTRAINED COLUMNS

Abstract

Stool widerflenge toluene thich are (subjected to en axial force and to end bending moments in the plane of their 'strung' aria generally fail by lateral- torsional buckling if they are not adequately braced laterally. 00001.100 of the presence of relatively high residua/ stressful in too-rolled' wide-flengo shapes. lateral-torsional buckling takes place when some portions of the column have already become inelastic for members in the practical length mangos The elastic and inelastic bchavicur of columns, with lateral supports provided by aide-rails connected to one liens.. of the column. hes been investigated.. The aide rails hove been Dammed to provide full lateral restraint, but provide no torsional regatta/at. A numerical solution using energy method hoe been obtained for a column cubjoctcd to axial lard and unequal terminal moments cad constrained to rotate about a longitudinal alas. rho aifccto of initial residual strosoos are Inca ludcd in the martin.
