【摘要】：通過拉拔試驗研究了HRB500鋼筋與RPC的粘結性能,基于試驗得出RPC與高強鋼筋的粘結滑移曲線。分別探討鋼筋直徑、保護層厚度、鋼筋錨固長度及強度等級對RPC與鋼筋粘結強度的影響。結果表明,鋼筋直徑越大、混凝土保護層越小、鋼筋錨固長度越大,則鋼筋與RPC的粘結強度越小。RPC與HRB500鋼筋的粘結強度高于其與HRB400鋼筋的粘結強度�；谠囼灲Y果,通過回歸分析建立RPC與HRB500鋼筋極限粘結強度計算公式,同時給出了RPC與HRB500鋼筋臨界錨固長度公式。
[Abstract]:The bond behavior of HRB500 steel bar and RPC was studied by drawing test, and the bond-slip curve between RPC and high strength steel bar was obtained based on the test. The influence of the diameter of steel bar, the thickness of protective layer, the length and grade of reinforcement Anchorage on the bond strength between RPC and steel bar is discussed. The results show that the larger the diameter of steel bar, the smaller the concrete cover and the longer the length of reinforcement Anchorage, the smaller the bond strength between RPC and RPC.The bond strength between RPC and HRB500 steel bar is higher than that with HRB400 steel bar. Based on the test results, the formula of ultimate bond strength between RPC and HRB500 steel bar is established by regression analysis, and the formula of critical anchoring length of RPC and HRB500 steel bar is given.
