Abstract

This study presents a general evaluation of the seismic response of concrete filled steel tube (CFST) bridge columns. Column to footing connection is considered as a critical design parameter, so available experimental results for different connections are discussed. With regard to the structural response of CFST bridge columns integrally connected to reinforced concrete (RC) footing, the data collected are divided into emulative connections (socket or grouted embedded connection and exposed connection) and non-emulative connection (prefabricated structural units that are connected together using post-tensioned tendons). With additional external confinement of the critical flexural zone of the socket connection, this system can ensure high drift capacity with a stable hysteretic response that is appropriate to moderate earthquake regions. However, due to the elastic response of its main components, very limited residual inclination and quick and easy replacement of damaged parts, hybrid rocking connection with buckling restrained steel plate (BRS) can be used in high seismic zones.
