| Abstract: | In this paper,the peeling behavior and the spalling resistance effect of carbon fiber reinforced polymer(CFRP) sheets externally bonded to bent concrete surfaces are firstly investigated experimentally.Twenty one curved specimens and seven plane specimens are studied in the paper,in which curved specimens with bonded CFRP sheets can simulate the concrete spalling in tunnel,culvert,arch bridge etc.,whereas plane specimens with bonded CFRP sheets can simulate the concrete spalling in beam bridge,slab bridge a... |
