CONSTRUCTION METHOD OF CONTINUOUS GIRDER BRIDGE, COMPOSITE FLOOR SLAB, AND CONTINUOUS GIRDER BRIDGE

摘要

PROBLEM TO BE SOLVED: To provide a preferable construction method of a continuous girder bridge by which (an absolute value of) the negative bending moment generated near a supporting point can be reduced etc., a composite floor slab which can be used in the method, and a continuous girder bridge constructed by the methods.;SOLUTION: (i) The composite floor slab 10 is arranged between the supporting points (bridge piers) 1 to form a simple girder bridge, and a floor slab concrete 11 is placed on each composite floor slab 10 between the supporting points 1, and then (ii) the space between the composite floor slabs 10 on the supporting point 1 is filled with concrete 4.;COPYRIGHT: (C)2008,JPO&INPIT
