BRIDGE STRUCTURE

摘要

A bridge structure is provided to maintain structural performance as it is and to improve economical efficiency by forming a bridge using a first girder member and a second girder member of a girder assembly without welding. A bridge structure(100) comprises a girder assembly(10) supporting load, and a concrete deck(50) compounded into the top of the girder assembly. The girder assembly comprises a first girder members(20), and a second girder member(30), wherein each girder member is provided with upper flanges(21,31), web plates(23,33) formed to be bent integrally from the upper flanges and lower flanges(25,35) formed to be bent integrally from the web plates, and the first girder member and the second girder member are arranged to be symmetric with each other along the transverse direction.
