Abstract:	摘要： Corrosion and deterioration of concrete piles are common problems for wharf structures. In Taiwan, corroded prestressed concrete (PC) piles supporting landing stage structures are frequently repaired and strengthened using carbon fiber-reinforced polymer (CFRP) jacketing. This paper presents an investigation on corroded and CFRP-repaired PC piles for landing stage structures. Seven reduced-scale PC pile specimens were tested to investigate their cyclic lateral load-carrying behavior. Four types of specimens were made to simulate four different levels of corrosion severity. Three corroded specimens were repaired using the CFRP jacketing prior to testing. The experimental results showed that the CFRP jacketing is rather efficient in terms of lateral strength, capacity for deformation and energy dissipation, and stiffness degradation, and is effective in repairing the seismic-resistance capacity of the corroded specimens. This study also conducted finite element (FE) analyses to analyze the tests of the seven specimens, achieving good corroboration between the analytical results and the tests. 出版者： Farmington Hills: American Concrete Institute 出版日期： 2012-09-01 出處： ACI structural journal, 2012-09, Vol.109 (5), p.715-715 版權： Copyright American Concrete Institute Sep/Oct 2012 識別號： ISSN: 0889-3241 識別號： EISSN: 1944-7361 識別號： DOI: 10.14359/51684049
