PRESTRESSED HYBRID WIDE FLANGE GIRDER SYSTEM ALLOWING CONTINUOUS CONSTRUCTION IN CONSTRUCTION STAGE

摘要

The present invention relates to a prestressed hybrid wide flange girder system allowing continuous construction in a construction stage, capable of resisting to a negative moment. According to one embodiment of the present invention, the prestressed hybrid wide flange girder system comprises: a wide lower flange which comprises prestressed concrete (PC) and to which a prestress is introduced; a buried steel frame web in which the bottom thereof is buried in the wide lower flange in order to expose a through-hole to the upper part of the wide lower flange; a cross section expanding upper flange to reinforce a compression zone; a gap spacing member formed at every predetermined interval in a longitudinal direction to connect both cross section expanding upper flanges; and a continuous steel structure formed to allow both upper plates to be bolt-coupled to the upper and lower plates of both adjacent prestressed hybrid wide flange girders, respectively.;COPYRIGHT KIPO 2018
