Title: Design of Double Composite Bridges using High Strength Steel
Authors: Shim, CS1 csshim@cau.ac.kr, Whang, JW2, Chung, CH3, Lee, PG4

Subjects: High strength steel, Iron & steel bridges, Strength of materials, Mechanical buckling, Iron & steel plates, Box beams, Bridge design & construction
Abstract: Abstract: High performance steel for bridges (HSB) which has higher performance in tensile, yield strength, toughness, weldability than common steels has been developed in Korea. HSB800 has a minimum tensile strength of 800MPa. However, design of long-span steel bridges with high strength steels is limited because of buckling and fatigue. In this paper, two concepts of composite and hybrid were utilized to solve the obstacles. Double-composite action in negative moment region was adopted to increase flexural stiffness of composite sections and to enhance buckling problems of steel plates. Combination of steel box girders and double-composite truss girders along the length of the bridges was also utilized to enable the design of longer span bridges. New continuous bridges with more than 100m span length were designed using the proposed concept and HSB. Effectiveness of each combination was discussed to suggest recommendations for the design of composite bridges with high performance steels. [Copyright &y& Elsevier]
