Abstract

Abstract

To improve the mechanical connection performance of fabricated structural joint, the material properties of polypropylene (PP) fiber grouting material and the mechanical properties of its rebar sleeve joint were studied. The mechanical properties of grouting material with different PP fiber contents and length were tested. The optimum content (Volume ratio to ordinary (JZ) grouting material) and length of PP fiber is 0.5% and 9 mm, respectively. Taking JZ grouting material as control group, the anchorage length of 4d, 6d and 8d (d is the diameter of bar) was set and the uniaxial tensile test was carried out. The bond stress distribution of PP fiber grouting material was also studied by using Bragg Grating sensors (FBG) and strain gauge. The results show that: The minimum anchorage length of rebar sleeve of PP fiber reinforced grouting material is more than 6d; PP fiber can effectively improve the joint toughness, enhance the bond anchorage effect of the sleeve, and improve the uniform distribution of the bond stress of the reinforcement, which shows “saddle” or “inclined ladder” distribution; the results of FBG sensor and strain gauge are basically consistent, and the accuracy of strain data collected by FBG sensor is higher than that of strain gauge.
