CONTINUOUS BEAM BRIDGE USING HYBRID GIRDER

摘要

PURPOSE: A continuous bridge using a hybrid girder is provided to reduce height and lengthen clear span by maximizing the advantages of compressive stress resistant concrete and tensile stress resistant steel. CONSTITUTION: A continuous bridge using a hybrid girder comprises three or more points including an abutment and pier and consists of a steel girder(SG) or a hybrid girder(HG). Only a steel girder consisting of a steel unit(110) is arranged on a general section, which is a positive moment section of the continuous bridge. A hybrid girder is arranged on a charging section, which is a negative moment section. The steel unit is as follows. A lower plate is formed on the lower part of an upper plate(111) side by side in a length direction. The upper and lower plates are connected by a connecting plate(112).
