dc.description.abstractRECENT INVESTIGATIONS RELATED TO PLATE GIRDERS DESIGN HAVE DEMONSTRATED THAT IS POS-SIBLE TO INCREASE THE FLEXURAL AND SHEAR RESISTANCE BY USING DELTA HOLLOW FLANGE GIRDERS. THIS TYPE OF REINFORCEMENT ALSO INCREASES THE TORSIONAL RIGIDITY OF THE PLATE GIRDER REDUCING LATERAL DEFOR-MATION. HOWEVER, THE IMPACT OF DELTA HOLLOW FLANGE GIRDERS SUBJECTED TO PATCH LOADING HAS RE-CEIVED LITTLE ATTENTION. THEREFORE, THIS PAPER AIMS AT STUDYING THE POSTBUCKLING BEHAVIOUR AND COM-PARING THE PATCH LOADING RESISTANCE OF LONGITUDINALLY STIFFENED AND DELTA HOLLOW FLANGE GIRDERS, EVALUATING THE INFLUENCE OF DIFFERENT GEOMETRICAL PARAMETERS SUCH AS THE PANEL ASPECT RATIO, THE PATCH LOADING LENGTH AND THE POSITION OF THE LONGITUDINAL STIFFENER. TO THIS PURPOSE, A NONLINEAR FINITE ELEMENT MODEL WAS DEVELOPED CONSIDERING GEOMETRICAL AND MATERIAL IMPERFECTIONS. THE COMPUTED ULTIMATE RESISTANCES ARE VALIDATED AGAINST EXPERIMENTAL RESULTS FOUND IN THE LITERATURE. BASED ON THE RESULTS, DESIGN RECOMMENDATIONS ARE PRESENTED FOR HOLLOW FLANGE GIRDERS UNDER PATCH LOADING.
