Abstract
In this paper, the comparative performance of repaired RC columns using steel and CFRP is presented. Also, the effect of transverse reinforcement ratio on the behavior of the steel and the CFRP repairing is investigated. Monotonic and cyclic load tests are conducted on nine RC column specimens with different repairing strategies and transverse reinforcement ratios to compare the load-displacement curves and the hysteretic behaviors. From the tests, it is observed that both steel and CFRP jacket repairings can significantly increase the displacement ductility and the ultimate load capacity of damaged columns. ࠀ Ā ࠀ 會Āࠀ ぅ?⨀ Ā ᐀ 會Ā᐀ 衅?⨀ ༀ Ā 저 會Ā저 ?⨀ 鎝 Ā ᐀ 會Ā᐀ 㡆?⨀ 衬鎝 Ā ᐀ 會Ā᐀ 遆?⨀ 偮鎝 瀀 ꀏ 會Ā ?⨀ Ā ᐀ 會Ā᐀ 䁇?⨀ 偒悗 Ā 㰀 會Ā㰀 顇?⨀ 悗 Ā ㈀ 會Ā㈀ ?⨀ 聓悗 Ā ᐀ 會Ā᐀ 䡈?⨀ ᡔ悗 Ā ᐀ 會Ā᐀ ꁈ?⨀ 끔悗 က Ā 저 會Ā저 ?⨀ 䣆 Ā 저 會Ā저 偉?⨀ Ā 저 會Ā저 ꡉ?⨀ 磇
