STRUCTURAL CHARACTERISTICS FOR STEEL-CONCRETE COMPOSITE BRIDGE PIER USING EMBOSSED H-SECTION STEEL AND PRECAST FORMWORK

Abstract

For more rationalization of construction and reducing the labor forces, steel-concrete composite bridge pier combined with embossed h-section steel and steel fiber reinforced precast formwork is developed. In this study, structural performance of this composite bridge pier is examined. Bending tests for beam specimens and cyclic tests for pier model specimens are carried out. As the result, followings are concluded, (1) the load capacity and load-displacement behavior of this composite structure can be evaluate by the same method with R. C. structure having the same reinforcement area, (2) the mechanism of ductility is suggested qualitatively and the practical methods of evaluating the ductility are proposed.
