EXPERIMENTAL STUDY ON ELASTOPLASTIC BUCKLING STRENGTH OF WEB IN I-SECTION GIRDER

The elastoplastic buckling strength of the web in I-section steel girder under pure bending was studied experimentally, the comparison between experimental and theoretical results was made. The influence of stiffness of longitudinal stiffener on buckling coefficients of the girder web was analyzed. And the reasonable ratios of height to thickness of the web were given and some items of the Chinese "Code for Design of Steel Structures" were discussed.
