<p>The present invention relates to a PSC I-typed girder in which cross section is optimized and a planning method thereof and, more specifically, to a conduction preventing block combined with a cross beam in a girder integral placing type for forming cross section to improve optimized efficiency and securing construction safety and structural safety of the girder as the cross section of the PSC I-typed girder is optimized to a geometrical shape of an upper flange and a lower flange, changing the thickness of the upper flange in a specific section in a longitudinal direction of the girder, applying additional optimized three-dimensional cross section, and reducing the number of girders arranged in a longitudinal direction of the bridge.</p> |
