ONE-BEHAVIOR 3D GIRDER BRIDGE

摘要

The present invention relates to a bridge which includes: a lower structure (40); a bridge bearing apparatus (60) disposed on the lower structure; and a saddle (50) disposed on the bridge bearing apparatus. The bridge further comprises: a bridge deck (10); a first girder (20) disposed on the lower side of the bridge deck in the longitudinal direction of the bridge deck and disposed on the upper side of the saddle to operate a load on the saddle; and a second girder (70) disposed on the external of a passage space above the bridge deck and connected to integrally move with the first girder in order to resist the operating load with the first girder.
