Abstract

Abstract Accelerated bridge construction (ABC) technology has been widely used due to its many advantages. However, the lack of well-developed and engineering proven connection details have limited the use of prefabricated substructures in seismic zones. The socket connection is one of many different ways of connecting precast substructure, which is characterized by convenient transportation and simple construction. This paper introduces the socket connections of precast bridge columns and reviews it from those aspects including theoretical research, experimental research and research on the application of advanced materials. The socket connection belongs to the emulative monolithic connections, which has good strength and ductility. But there exists a disadvantage of large residual displacement after the earthquake for socket connection. At present, there are many researches on the design of socket connection, but there are few studies on the repair of piers after the earthquake. Therefore, it is necessary to study a quick and economic repair method in the future to exert the functionality of bridge structures following earthquake event.
