<p>A prestressed steel composite girder and a method of manufacturing the prestressed steel composite girder are provided by using a steel beam and a concrete. The method includes steps of: placing the steel beam above the ground; installing a form, into which the concrete is to be inserted, to surround at least a portion of the steel beam, the form being suspended by the steel beam; inserting the concrete into an internal space of the form and curing it; and removing the form to compose the steel beam and the concrete. The prestressed steel composite girder includes a steel beam and a concrete composed to surround a portion of the steel beam so that stress caused by its self- weight can be applied on only the steel beam.</p> |
