STRENGTH OF LONGITUDINALLY STIFFENED PLATE GIRDERS UNDER COMBINED LOAD

A METHOD IS DESCRIBED FOR DETERMINING THE STATIC ULTIMATE STRENGTH OF LONGITUDINALLY STIFFENED PLATE GIRDER PANELS SUBJECTED TO A COMBINATION OF SHEAR AND BENDING. THE METHOD IS APPLICABLE TO SYMMETRICAL, UNSYMMETRICAL, HOMOGENEOUS AND HYBRID GIRDERS. COMPATABILITY OF THE DEFORMATIONS IS MAINTAINED BETWEEN THE TWO WEB SUBPANELS INTO WHICH THE WEB IS SUBDIVIDED BY THE LONGITUDINAL STIFFENER. IT IS ASSUMED THAT THE ULTIMATE STRENGTHS OF THE WEB SUBPANELS AND OF THE FRAME FORMED BY THE STIFFNER AND FLANGES CAN BE COMPUTED SEPARATELY AND THAT THE ULTIMATE STRENGTH OF THE WHOLE PANEL IS A SUM OF THE STRENGTHS OF THESE COMPONENTS. A CONTINUOUS INTERACTION RELATIONSHIP IS OBTAINED BETWEEN SHEAR AND MOMENT PRODUCING THE ULTIATE CONDITION OF THE GIRDER PANEL. COMPARISON OF THE COMPUTED LOADS WITH AVAILABLE TEST RESULTS INDICATES THAT THE PROPOSED APPROACH PROVIDES A RELIABLE MEANS FOR COMPUTING THE ULTIMATE STRENGTH OF LONGITUDINALLY STIFFENED PLATE GIRDERS. /AUTHOR/
