Title:
UPPER STRUCTURE OF COMPLEX-TYPE BRIDGE
Document Type and Number:
WIPO Patent Application WO/2024/058286
Kind Code:
A1
Abstract:
The present invention relates to an upper structure of a complex-type bridge. In a connecting portion between a truss girder and a steel box girder having different types, the connecting material of the truss girder comprises: a first diagonal material which extends to connect from a first position of the lower chord of the truss girder, the first position being closest to a boundary between an overlapping region and a first region, to an upper chord to be upwardly inclined in a first direction away toward the first region; a second vertical material connecting vertically from the first position toward the upper chord; and a third diagonal material which extends to connect from a second position where the vertical material and the upper chord meet each other to the lower chord to be downwardly inclined in a second direction opposite to the first direction, so that both cross-sections of the lower chord and the upper chord adjacent to a diaphragm act as structural members. Thus, as both cross-sections of the upper chord and the lower chord that are adjacent to the diaphragm act as structural members while reducing an overlapping length in which the truss girder and the steel box girder overlap each other, a load may be transferred without blocking the flow of stress due to the upper chord and the lower chord, and a phenomenon in which stress is concentrated on a certain member may be prevented.
