Abstract
<p>The authors devised a double-square joint (referred to as DS joint) as a bar joint structure capable of avoiding the bar interference when precast beams are installed, and reducing the joint width between the precast beams. For DS joint, U-shaped bars are protruded from the end surface of the precast beams. After setting those U-shaped bars abutted, square shaped bars are inserted to overlap and form a joint with the U-shaped bars. In this study, bending load test of the precast beam with the DS joint was carried out, and the flexural capacity and crack behavior of the DS joint structure were clarified. Furthermore, FEM analysis was conducted and the flexural capacity mechanism of the DS joint composed of closed bar shape was discussed.</p>
