PROBLEM TO BE SOLVED: To provide a displacement preventing structure of a composite structure using a highly strong steel fiber reinforced concrete by which shear strength per perforated steel plate dowel is improved without using a through reinforcement.SOLUTION: In a displacement preventing structure of a composite structure to make the composite structure by arranging a steel shell 13 between a steel girder 11 of a bridge and a reinforced-concrete bridge pier 10 or between the steel girder 11 and a prestressed concrete girder 20, and then filling the steel shell 13 with concrete to join the steel girder 11 to the reinforced-concrete bridge pier 10 or the steel girder 11 to the prestressed concrete girder 20, the perforated steel plate dowels 14 are arranged on an inner surface of the steel shell 13, and the inside of the steel shell 13 is filled with the highly strong steel fiber reinforced concrete containing silica fume and a steel fiber. |
