1/2 축소된 원형교각의 GFRP 래핑 내진보강
Seismic Retrofit of 1/2 Scale-down Circular RC Columns with GFRP Wrapping
초록
This paper presents experimental studies on investigating the seismic retrofit performance of reinforced concrete circular columns with poor lap-splice details using GFRP wrapping. Four 1/2 scale-down model columns have been tested. The as-built column is expected to suffer brittle failure due to the bond failure of lap-spliced longitudinal reinforcement. The retrofitted columns using GFRP wrapping showed significant improvement of seismic performance.
