Abstract

In order to investigate the mechanical properties of half grout sleeve splicing for rebars,14 specimens were tested under static tension,with such main parameters as bar diameter,sleeve dimension and rebar deviation being considered.The results show that ( 1) the tested half grout sleeves meet the strength requirements well; ( 2) the specimens are destroyed in three failure patterns including the tension fracture of the rebar,the rebar scratchplough pulling out of the rebar and the sliding wire of the sleeve; and ( 3) when the tension fracture of the rebar occurs,the rebar deviation has little effect on the bearing capacity of specimens.Based on the analysis of the test results,a design method is put forward to avoid the occurrence of the rebar scratch-plough pulling out and the sleeve sliding wire.
