STUDY ON JOINTLESS BRIDGE CONSTRUCTION IN JAPAN

Japanese experience with embedded and combined-type jointless methods of bridge construction is reviewed. During recent decades, several Japanese public authorities made concerted efforts to develop a bridge construction method, to eliminate expansion joints by paving or partially combining bridge sections, thus achieving a continuous and smooth road surface. This resulted in the development of several jointless construction methods for existing short-span bridges. Jointless methods can be classified approximately into: (1) methods using embedded-type joints: (a) expansion absorbing type; (b) expansion dispersing type; and (c) expansion inducing type; and (2) combined-type jointless methods: (a) main beam connection method; (b) floor slab connection method; and (c) crossbeam connection method. The major features of embedded-type joints are outlined in a table and a conceptual diagram. The combined-type method joins together the members of adjacent beams, to transmit the temperature-induced displacement towards the bridge axis to the adjacent beams. Its three variants are used with steel beam and concrete beam types of bridge. For the covering abstract see IRRD 873218.
