| Abstract |
Recently, new moment-resisting precast concrete beam-column joint was proposed for moderate seismic regions. It has the connection reinforcing bars, penetrated the joint and lap-spliced with the bottom bars of precast U-beam. In this study, to evaluate the performance for noncontact lapped splice, experimental and analytical works were conducted. Major variables for tests and FEM analysis were the length of lap(0.8lb, 1.0lb, 1.2lb, 14lb) and the diameter of connection reinforcing bars(D19, D22, D25). Results of experimental and analytical works show that the these variables has much influence on strength and ductility, and deformation of lapped joint. Particularly, the size of splice bars had an effect on the splice performance of the vertical noncontact lapped bars. |
