A innovative technique for retrofitting reinforced concrete(RC) columns using prestressing steel strips(PSS) was introduced,and quasi-static tests of reinforced concrete column retrofitted by this new method under high axial-compression ratio were conducted.In the quasi-static test of these four retrofitted concrete column specimens,the influence on specimens' seismic performance of axial-compression ratio and spacing of the steel strips were studied.And based on the test results,the seismic performance indexes such as characteristic of resilience,skeleton curve,ductility coefficient and energy consumption were all analyzed and discussed.It could be concluded that this innovative retrofit technique could markedly improve the column's deformation ability and ductility,so as to improve the column seismic performance.
