GIRDER CONSTRUCTION TECHNIQUE BY BUOYANCY

摘要

PURPOSE: A girder bridge construction method using buoyancy is provided to reduce the size and format height of a cross section by making stress stay on necessary location. CONSTITUTION: A girder bridge construction method using buoyancy is as follows. A steel composite girder(SCG) of a positive moment section is manufactured. The steel composite girder of a negative moment area is manufactured. The steel composite girders of the positive moment section and negative moment area are interlinked. The connected steel composite girders of the positive moment section and negative moment area are on a pier(P) or abutment(A). A cross member and an end beam are established on the steel composite girders of the positive moment section and negative moment area.
