ON THE CONTINUOUS COMPOSITE GIRDER

A MARKED INCREASE IN MOTOR TRAFFIC IN POSTWAR JAPAN HAS MADE CONSTRUCTION AND IMPROVEMENT OF ROADS AN URGENT NECESSITY. IN THE COST OF CONSTRUCTING A ROAD, THE STRUCTURES, SUCH AS BRIDGES AND TUNNELS, CONSTITUTE A LARGE SEGMENT AND WAYS OF CONSTRUCTING THEM MORE ECONOMICALLY ARE AN IMPORTANT CONSIDERATION IMPOSED ON THE ENGINEERS. COMPOSITE BRIDGE CONSTRUCTION, DEVELOPED RAPIDLY IN THE POSTWAR ERA, HAS MADE A REMARKABLE CONTRIBUTION TO THE PROBLEM OF ECONOMICAL DESIGN. ABOSHI BRIDGE, THE FIRST EXAMPLE OF THE CONTINUOUS COMPOSITE GIRDER BRIDGE IN JAPAN, IS OF THREE-SPAN (3 AT 32M) DESIGN, IN WHICH, COMPARED WITH A NONCOMPOSITE CONTINUOUS GIRDER, THE WEIGHT OF STEEL USED AND THE CONSTRUCTION COST WERE REDUCED BY 14 AND 10 PERCENT RESPECTIVELY. FOLLOWING THIS PIONEER WORK, A NUMBER OF CONTINUOUS COMPOSITE GIRDER BRIDGES HAVE BEEN CONSTRUCTED IN JAPAN. THIS PAPER DESCRIBES THE DESIGN, ERECTION, AND VARIOUS FIELD TESTS OF THE ABOSHI BRIDGE. /AUTHOR/
