Abstract：
In order to understand the rationality of the U-closed reinforcement connection of the precast concrete structure, two U-shaped closed tendon specimens and a were designed in uniaxial pressure loading test. The results show that：the U closed reinforcement connection can effectively transfer axial stress, the slip is not apparent in joint between cast-in-place with precast surface before the destruction of the specimen, the phenomenon of drum flexor tendon does not appear when U-closed specimen is damage,the failure modes is close to the cast-in-place specimen. The U-closed closure reinforcement connection in axial pressure is reliable.
