콘크리트 충전 강관으로 보강된 철근콘크리트 기둥의 내진성능

The object of this study is to review hysteretic characteristics of RC column that increase seismic performance by attaching CFT(Concrete Filled Steel Tube). For the attainment of this purpose, Static test and FE- Analysis for column under lateral cyclic loading and constant axial load were conducted. Push over curve obtained from FE-analysis using ATENA 3D corresponds with hysteretic curve of experimental data. And then structural stability and superiority for retrofitted RC members in terms of strength enhancement is verified
