STEEL-PC HYBRID BEAM AND MANUFACTURING METHOD THEREOF

摘要

The present invention relates to a steel-PC hybrid beam and a manufacturing method thereof which maximize a combination effect by assembling a lower flange member made of precast concrete and a steel web member, have excellent prestress introduction efficiency, and improve economic efficiency. The steel-PC hybrid beam of an overall U-shape is filled with concrete, and comprises: a lower flange member which is a precast concrete member disposed on a lower portion of a hybrid beam in a longitudinal direction of the hybrid beam and provided with a PS steel wire disposed therein in the longitudinal direction to introduce prestress on the lower portion of the beam; and a pair of web members of steel plates arranged on both sides of an upper surface of the lower flange member in parallel with each other and separated from each other.
