- Synopsis:
- This research attempted to grasp flexural capacity of RC (Reinforced Concrete) beams connected with loop-shaped re-bar joints through experiments of one-way bending and alternating bending. As the experimental results, it became clear that the RC beams connected with the loop-shaped re-bar joints have enough abilities in both flexural capacity and energy absorption, if compared with the RC beams having usual lap splice joints or continued re-bars. In addition, the effects of arrangements of loop-shaped re-bars, reinforcements inside the loops, and so on are discussed in this paper.
