A new retrofitting system for wall type bridge pier has been developed. Significant feature of this system is that pier wall can be efficiently confined by hoop-tension of multi-cylindrical steel segments with less number of tie-boltings than the ordinal steel jacketting method. The experimental result indicates that new system ensures more significant improvement in ductility capacity. This paper finally proposes practical design formula for ductility capacity assessment of bridge piers retrofitted by the present system.
