PRESTRESSED COMPOSITE GIRDERS AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A pre-stressed steel composite girder and a manufacturing method thereof are provided to reduce the use of steel material through efficient material combination by improving a manufacturing method of a steel composite girder. CONSTITUTION: A pre-stressed steel composite girder comprises a steel composite member(10), and a tension member(30). The steel composite member is formed by compositing a steel girder(12) and concrete. The steel girder is extended along the longitudinal direction. The tension member includes the precast concrete(20). The precast concrete is extended in the longitudinal direction from both sides of the steel girder.
