An Experimental Study on the Seismic Performance of RC Piers using High-strength Concrete and High-strength Rebars

고강도콘크리트와 고강도철근을 사용한 교각의 내진거동 실험연구

Five RC piers were tested under a constant axial load and a cyclically reversed horizontal load to investigate the behavior of RC piers used in the high-strength concrete and the high-strength rebars. Seismic design of piers were conducted under the same design, according to the current Korean Bridge Design Standard. The parameters of the test were concrete compressive strength and steel strength, steel ratio. The test results indicated that RC piers of the high-strength concrete and high-strength rebars exhibited ductile behavior and seismic performance.
