摘要

PURPOSE: A PSC girder which is open on the bottom and includes support partitions and a simple bridge or continuous bridge construction method using the same are provided to minimize the frictional resistance of tendons and efficiently arrange the tendons according to the span of a bridge. CONSTITUTION: A PSC girder(100) comprises an upper plate(110), two side walls(120), support partitions(130), and tendons(200). The upper plate is extended lengthwise. The side walls are extended downward from both ends of the upper plate and extended lengthwise. The support partitions are extended transversely in an open space between the side walls and vertically separate from each other. The tendons are installed through tendon passage holes of the support partitions and arranged lengthwise in the open space.
