GRAPHICAL ASSESSMENT TECHNIQUE FOR THE SPAN OF PRESTRESSED CONCRETE GIRDER BRIDGE

摘要

PURPOSE: A graphical assessment technique for the span of a prestressed concrete girder bridge is provided to facilitate the evaluation of contribution applied on the increment of span. CONSTITUTION: A graphical assessment technique for the span of a prestressed concrete girder bridge comprises following steps. A design possible area is drawn out based on an allowable stress design in a PSC girder by displaying a safety evaluation equation as a graph according to span and the number of tendons.
