摘要: Elastic distortional buckling is one of the essential modes I-steel concrete composite beam (ISCCB); such often occurs under gradient negative moment. The key factors affecting kind are "torsional" and "lateral" restraint stiffnesses bottom flange beam. This paper investigates equivalent lateral torsional ISCCB relations for estimating used to determine critical stress associated moment A new method proposed assessing elastic-foundation beam, by which related considered: (1) coupling effect between applied forces lateral/torsional stiffness (2) a (3) shear deformation web. has been compared with those available using data 15 cases different loading conditions; results show that present much more accurate reliable than existing ones. as herein recommended further research in relation ISCCB.
