Influence of Horizontal Curvature on the Shear Resistance of Steel Plate Girders with Slender Webs

Steel plate girders have been used as bridge structural components for over two hundred years. Given technology and material advancements, steel plate girders and their elements (webs and flanges), continue to become slenderer. As a result, elastic buckling is a concern when evaluating shear capacity. This issue has been addressed for straight girders by a number of researchers, most notably via the development of the theory of tension field action (TFA). To date, horizontal curvature effects have not been included in design of steel bridges, however others have investigated horizontal curvature effects on slender, shear panel behavior and capacity (1). This paper summarizes an ongoing study investigating how horizontal curvature influences the shear buckling capacity and ultimate shear resistance in steel plate girders with slender webs. Results show that horizontal curvature can affect the shear capacity and a proposed shear buckling coefficient produces accurate results.
