An experimental investigation was conducted to study the seismic performance of half precast beam-column joints. A composite structure was developed for beams, in which the exterior was a U-shaped precast element and the interior was concrete cast in-situ. Four interior beam-column subassemblages were tested under simulated seismic loads. The behavior differences concerning the strength, ductility, stiffness, energy dissipation, and bond deterioration at the beam-column joints are presented. Tests results indicated that the proposed method of connection showed an adequate structural performance when the subassemblage was subjected to large cyclic inelastic deformations. |
