FLANGE BUCKLING STUDIES

AN ANALYTICAL STUDY OF THE BUCKLING BEHAVIOR OF THE FLANGE OF HORIZONTALLY CURVED PLATE GIRDERS IS PRESENTED. BUCKLING IN BOTH THE ELASTIC AND INELASTIC RANGE IS CONSIDERED. THE INFLUENCE OF RESIDUAL STRESSES RESULTING FROM THE FABRICATION PROCESS ARE INCLUDED. THE MATHEMATICAL MODEL IS DEVELOPED USING ORTHOTROPIC PLATE THEORY AND SOLVED BY MEANS OF FIRST ORDER FINITE DIFFERENCES. THE INFLUENCE OF THE VARIOUS PARAMETERS WHICH AFFECT THE BUCKLING STRESS IS ILLUSTRATED. DESIGNN RECOMMENDATIONS FOR THE FLANGE DIMENSION (WIDTH TO THICKNESS RATIO) REQUIRED TO PREVENT LOCAL BUCKLING ARE ALSO GIVEN. /AUTHOR/
