ABSTRACT
The structural composition of the improved CFRP tendon bonded anchor is introduced. Based on the improved finite element model of anchorage structure, relevant elasticity analysis is carried out. At different loading levels, the distribution and changes of axial stress and surface bonding stress of CFRP tendons show obvious regularity. CFRP tendons at the ends of steel pipes are easy to break, which is the disadvantage of this type of anchor. A buffer zone is still to be set at this location to reduce local stress.
