Summary:The present invention relates to a prestressed concrete girder (PSC girder) manufactured for improving longitudinal compression strength by applying lateral tensile strength to a girder to which longitudinal tensile strength is applied. The PSC girder comprises: a longitudinal tensile material arranged therein to apply longitudinal tensile strength thereto; and a lateral tensile material which penetrates the upper or lower flanges of the PSC girder for increasing longitudinal compression strength of the PSC girder and which is disposed to apply lateral tensile strength to the PSC girder.
