Strengthening Effect Evaluation Technique of R/C Beams using the Vibration Test

진동시험을 통한 R/C Beam의 보강효과 검증기법

This study suggests a strengthening effect evaluation technique of reinforced concrete beams using the vibration test. To evaluate the strengthening effect of R/C beams, Strengthening Factor(Sf) was suggested. Using the value of Sf, 20 beams were evaluated. According to these results the effects of R/C beams strengthened by steel plate is superior than those of R/C beams strengthened by carbon fiber sheet.
