An experimental study on seismic behavior of precast concrete beam-column joints is presented in this paper. The objective of this study is to investigate the of seismic behavior of a newly developed precast concrete system that can make the connections more economical and easily constructed. This system is that the concrete joints are at the member ends, and the bars connections are located at the middle of precast members where the stresses are small. Nine two thirds scale beam-column joint specimens representing a portion of a frame, including one monolithic, were tested under simulated seismic action. The behavior with respect to bending strength of beams, shear strength, bond deterioration at the beam column joint core, and energy dissipation are presented and discussed. Test results indicate that the proposed method of construction presents an adequate strength,and ductility when subjected to large inelastic deformations under cyclic loads.
