ABSTRACT:
A construction method for simple bridges or continuous bridges using prestressed concrete girder (PSC girder) and precast slabs (PSC slabs) where prestress is applied to the lower portion of the center of the girder. bridges of low clearance and long span are constructed by preventing a loss of prestress due to load of the slabs and relieving excessive compression force generated on the upper edge portion of the center of the girder during the construction of the bridge.
