Abstract

Abstract

In order to colligate the virtue of bonding-anchor and wedge-anchor,the wedge-bond anchorage for CFRP tendons was investigated,which was made by bonding and wedge parts, working in parallel．Based on the characteristics of exiting CFRP tendon anchors and according to a series of static load tests,it was studied the bonding property of colloid,and the influence of bond length,colloids thickness on the performance of straight pipe bonding anchorage．The static load test of wedge-bond anchorage was conducted to investigate its failure mode,ultimate load,slip deformation,etc．Transport mechanism of anchorage stress is preliminarily analysed according to variation of actual stress in the anchorage zone．The influences of variation in specific parameters,such as wedge slope,angular differential,presetting load,on the internal stress of the anchorage were simulated by using finite element method．And the suggested design parameters were offered．Which can provide academic reference for the optimization of wedge-bond anchorage．
