BUCKLING OF UNSTIFFENED CURVED PLATES

AN ANALYTICAL STUDY OF THE BUCKLING BEHAVIOR OF THE UNSTIFFENED COMPRESSION FLANGES OF HORIZONTALLY CURVED BOX GIRDERS IS PRESENTED. THE CURVED PLATE ELEMENT IS ASSUMED TO BE SIMPLY SUPPORTED AND SUBJECTED TO A COMBINATION OF IN-PLANE NORMAL AND SHEARING STRESSES. THE EIGENVALUE PROBLEM IS FORMULATED USING THE ENERGY EXPRESSION FOR THE BUCKLED PLATE AND SOLUTIONS ARE OBTAINED BY MEANS OF THE RAYLEIGH-RITZ METHOD. IN INELASTIC RANGE, THE ORTHOTROPIC NATURE OF THE PLATE BEHAVIOR IS UTILIZED. DESIGN RECOMMENDATIONS FOR THE FLANGE DIMENSIONS (WIDTH-TO-THICKNESS RATIO) REQUIRED TO PREVENT LOCAL BUCKLING ARE ALSO ESTABLISHED. /AUTHOR/
