Abstract:
Anchorage of externally bonded reinforcement is the main problem for strengthening concrete structures with CFRP strips - Štepánek & Šustalová (2000, 2001). This paper describes a form of the tests and some results implicating from different properties of anchorage elements. The test results are compared with values obtained from mathematical analysis of anchorage zones behaviour and normal stress distribution along the anchorage length. Design of the anchorage zones is very important part at the calculation of CFRP strips reinforced structures. The design method of bond length differs in various standards. The results of calculations stated in this paper were obtained according to CSN standard system.
