Seismic Performance Study of Self-Centering Steel Reinforced Concrete Building Joints Under High-Intensity Earthquake

The better the seismic performance of building joints, more lives and property can be preserved in earthquake disasters. This paper briefly introduced the basic structure self-centering reinforced concrete (RC) column-steel beam joints then prepared three types joint specimens. Specimen 1 was a self-centering RC column-steel joint, specimen 2 obtained by removing damping core plate based on 1, 3 removing both prestressed reinforcement 1. The quasi-static loading tests were carried out three specimens, followed vibration with an eight-degree a table. The findings demonstrated that had higher peak load ultimate displacement when quasi-static displacement greater than yield displacement; energy dissipation capacity when facing periodic loading; earthquake, specimen 1 had best ability.
