MANUFACTURING METHOD FOR STEEL-CONCRETE COMPOSITE BOX GIRDER CONTINUOUS GIRDERS

摘要

PURPOSE: A method for manufacturing a steel composite box continuous girder is provided to maintain twist resistance and reduce steel amount by improving the connection relation between a positive moment girder and a negative moment girder. CONSTITUTION: A method for manufacturing a steel composite box continuous girder comprises followings. Manufactured is a positive moment girder(100) functioning as a tensile member and having steel bars(24,34) and the exposed part of steel girders(10,30). Concretes(28,38) are applied so that a negative moment girder(200) functioning as a compression member is manufactured. The positive moment girder and the negative moment girder are longitudinally placed so that a continuous girder is manufactured. Concrete is poured in the exposed part and the negative moment girder.
