INSTABILITY OF HORIZONTALLY CURVED MEMBERS-BENDING BEHAVIORS OF CYLINDRICAL WEB PANELS

THE STRESS DISTRIBUTION IN CYLINDRICAL WEB PANELS OF HORIZONTALLY CURVED GIRDERS SUBJECTED TO AN APPLIED MOMENT IS STUDIED ANALYTICALLY. BOTH THE MEMBRANE STATE OF STRESS IN THE PLANE OF THE WEB AND THE WEB BENDING STRESSES RESULTING FROM THE CURVATURE OF THE PANEL ARE CONSIDERED. A SIMPLIFIED MATHEMATICAL MODEL WHICH TREATS THE WEB AS A SERIES OF CURVED STRIPS (ARCHES) IS USED. SOLUTIONS FOR THIS MODEL ARE OBTAINED USING THE RAYLEIGH-RITZ METHOD. THE INFLUENCE OF CURVATURE ON THE RESULTING STRESSES IN CURVED WEBS IS PRESENTED. DESIGN RECOMMENDATIONS FOR THE ALLOWABLE BENDING STRESSES IN CURVED BEAMS, EXPRESSED IN TERMS OF THE WEB DEPTH-TO-THICKNESS RATIO, ARE ESTABLISHED. /FHWA/
