Abstract
CFRPs have proved as outstanding engineering materials in the aircraft / aerospace industry. This enables them to become an alternative material for the use in reinforced concrete structures. Experimental and numerical investigations on different anchoring systems for a stranded CFRP-cable used as a prestressing element are presented. Clamping and potting systems have been developed for single cables. They were tested and optimized under static and cyclic tension loading. The results of the finite element analysis help to give a better understanding of the complex stress distribution in the anchoring zone in order to optimize it. The comparison between experimental results and FE analysis of a clamping system showed good agreement. The behavior of the optimized clamping system under static and cyclic loading encourage practical field tests and further investigations.
