RESEARCH ON THE PLANTED BAR BONDING PERFORMANCE UNDER THE CYCLIC LOADING

Chemically planted bar in concrete structure is a new style post-embedding technique，but there are few researches for the planted bar stress status under the dynamic load at present． By combining with the chemical bonding mechanism of planted bars under the static force at home and overseas，experimental study on the planted bars specimen adhesive properties was corried out under low cycle load． The displacement-load，strain-load hysteresis curves and the axial strain and bond stress curves of the planted bars through four concrete specimens bond performance tests under low cycle load were got and analyzed，some relative conclusions of the planted bars adhesive properties under the dynamic load were obtained．
