Experimental Study on Bond Splitting Strength Of All Lap Splices Of Main Reinforcing Steel Bars Lapped In Beam Depth Way

摘要

many of previous studies regarding main reinforcing steel bars (rebars) lap splice describe the respective rebars as being lapped side by side (horizontal splicing). The case of lap splice in which the respective spliced rebars are lapped by placing one on top of the other (vertical splicing), as used in precast shell form system, etc., are still not too clear. In order to comprehend the bond splitting strength of vertical splicing, a pure bending test was conducted. The test parameters were the transverse reinforcement ratio and existence of inner supplementary tie.
