dc.description.abstractCURRENTLY, THERE ARE DIFFERENT OPTIONS TO INCREASE THE ULTIMATE RESISTANCE OF PLATE GIRDERS SUBJECTED TO PATCH LOADING. SOME OF THESE ALTERNATIVES INCLUDE THE USE OF CLOSELY SPACED TRANSVERSE STIFFENERS AND THE USE OF LONGITUDINAL STIFFENERS. NEVERTHELESS, RECENT INVESTIGATIONS HAVE DEMONSTRATED THAT THE RESISTANCE IS ALSO IMPROVED BY USING DELTA STIFFENERS, WHICH ARE OBTAINED BY WELDING TWO PLATES BETWEEN THE WEB PLATE AND THE LOADED FLANGE. THIS PAPER AIMS AT STUDYING THE ELASTIC BUCKLING BEHAVIOR OF SLENDER PLATE GIRDERS DESIGNED FOLLOWING AASHTO NORMS WITH DELTA STIFFENERS SUBJECTED TO PATCH LOADING. THE RESEARCH IS CARRIED OUT BY MEANS OF EIGENVALUE ANALYSIS USING THE FINITE ELEMENT METHOD. A PARAMETRIC STUDY IS PERFORMED TO EVALUATE THE INFLUENCE OF VARIOUS GEOMETRICAL PARAMETERS ON THE BUCKLING COEFFICIENT OF THE GIRDER. FINALLY, DESIGN RECOMMENDATIONS ARE SUGGESTED BASED ON THE OBTAINED RESULTS.
