Experimental evaluation of CFRP anchorage systems

Natasha Cristina da Silva Costa, Dênio Ramam Carvalho de Oliveira

Abstract


This paper evaluates the experimental behavior of anchorage system for carbon fiber reinforced polymer (CFRP) as structural strengthening. Tests on 13 specimens were carried out using different types of anchorage system, besides straight anchorages. All proofs were tested using a reaction cage to avoid rotations, guaranteeing predominantly tensile forces on the proofs. Yielding loads, failure loads and modes, besides cracking patterns are presented and analyzed. Experimental results showed that the specimens with additional anchorage presented greater final strength than those with straight anchorage, and for these specimens while the straight anchorage lengths were increased the stress values tended to be equal to 1,0 MPa. The additional systems to improve performance of straight anchorages increased the strengthening efficiency up to 88 %.

Key words: Anchorage, CFRP, Carbon Fiber.
