Abstract
This paper describes reports the mechanical performance of the new rigid joint system of PCaPC member and cast-in-place bottom slab .This rigid joint is PRC structure which is to connect the PC bar and reinforcement to the special metal anchor plate embedded in the PCaPC member and to introduce tensioning force to the joint face, and this rigid joint has the restoration performance. The static loading test using the full scale model shows as follows: 1) this rigid joint is able to be designed using the same method as the joint-less structure and has seismic performance and anti water leak performance same as the joint-less structure, 2) this metal anchoring system is designed by our original design concepts with structural appropriateness for Level 1 earthquake ground motion and the ultimate load.
