Pseudo Dynamic Test Research on the Seismic Performance of RC Bridge Piers Retrofitted with Fiber Sheet
섬유보강 RC교각의 내진성능에 관한 유사동적실험 연구
Abstract
The objective of this experimental research is to assess the seismic performance of circular RC bridge pier specimens retrofitted with fibers which were designed as a prototype of Hagal bridge in the city of Suwon, Korea. Pseudo-dynamic test has been done for two nonseismic test specimens which were nonseismic designed by the related provisions of the Highway Design Specification, and four nonseismic test specimens retrofitted with fibers in the plastic hinge region. Important test parameters were load patterns, and retrofit. The seismic behavior has been analyzed through the displacement ductility, energy analysis, and capacity spectrum. Approximate 7.0 displacement ductility was observed for nonseismic test specimens retrofitted with fibers. It is concluded that these retrofitting test specimens could have sufficient seismic capacity in the region of moderate seismic zone.
