HIGH EFFICIENCY PRESTRESSED CONCRETE GIRDER BY STRAND LINEAR ARRANGEMENT
The present invention relates to a high-efficiency prestressed concrete (PSC) girder by a linear arrangement of a strand. For this purpose, the high-efficiency PSC girder by the linear arrangement of a strand in accordance to an embodiment of the present invention is a reinforcing rod concrete PSC girder with a post-tension method having a plurality of strands arranged therein having an I-shaped section on an upper and a lower flange and a web. Two strands are arranged linearly such that the PSC girder can penetrate the lower flange. The two strands arranged linearly on both end parts of the lower flange are fixated by means of a lower fixture. An upper strand is arranged parabolically to sequentially penetrate the lower flange, the web, and the upper flange from a center of the PSC girder towards both end parts. A protrusion part is formed above both end parts of the upper flange. The parabolically arranged upper strand is fixated to both end parts of the protrusion part by means of a protruding fixture.
