Abstract

Abstract

The influence of residual stress on stainless steel beams is to cause premature yield and loss of flexural stiffness.The influences of magnitudes and distribution of residual stress on the lateral buckling are therefore important for stainless steel welded I-beams.The influencing factors analysis on the inelastic lateral buckling behavior of the beams was presented by adopting the widely approval model of residual stress.This paper improves the investigation on the overall buckling behavior and the results show that the amplitude of compression stress in flange performs the significant effect．
- residual stress,
- stainless steel,
- welded I beams,
- lateral-torsional buckling
