| Summary: | 碩士 === 逢甲大學 === 土木及水利工程研究所 === 88 === The purpose of this study is to evaluate the seismic resistance of old wall piers and to retrofit the piers using CFRP. The characteristics of old wall piers are low longitudinal and transverse steel value. There are four wall pier models designed in this study. Two of them are as-built models exerting repeated force in the long and short direction. Others exerting repeated force in the long and short direction are strengthened by carbon FRP and compare with above as-built models. Based on the results of cyclic loading tests, it is concluded that old wall piers may not perform well. Wall pier exerting repeated force in the long direction has major improvement after it is strengthened by CFRP. But wall pier exerting repeated force in the short direction does not have obvious improvement after it is strengthened by CFRP.
