A new seismic retrofit technique utilizing PC bar prestressing was proposed as one of techniques in order to prevent shear failure and improve ductility of RC columns in the previous paper by authors The purposes of this investigation are to evaluate the lateral capacity and to propose the design method of RC columns retrofitted by PC bar prestressing as external hoops on the base of cxpenmental test results under the combination of cyclic lateral forces and a constant axial load whose level to concrete cylinder strength ratio is 0 2 These test results consist ofa total of 31 specimens whose failure modes are shear, flexural and bond failure ones As a result, if seismic retrofit technique by PC bar prestressing is designed so that shear and bond strength of the retrofitted columns can overcome their flcxural strength, a desirable seismic performance may be expectcd for seismic retrofit of RC columns
