The condition of uniaxial stress is closely approximated in prismatic bars subjected to pure axial tensile.
单轴的应力状态跟棱柱杆承受单纯轴向拉伸十分近似。

Results indicate that the ultimate bond stress between bars and RPC decreases with the increase of bar diameter or with anchorage length when bar diameter is the same.
Based on the design code of concrete structure (GBJ10-89), the paper gives the nominal tensile stress method of controlling crack width in prestressed concrete structure of punchy bars.
