The experimental work on two full-scale precast concrete beam-column corner joints with corbels was carried out and their seismic performance was examined. The first specimen was constructed without steel fiber, while second specimen was constructed by mixed up steel fiber with concrete and placed it at the corbels area. The specimen were tested under reversible lateral cyclic loading up to ±1.5% drift. The experimental results showed that for the first specimen, the cracks start to occur at +0.5% drifts with spalling of concrete and major cracks were observed at corbel while for the second specimen, the initial cracks were observed at +0.75% with no damage at corbel. In this study, it can be concluded that precast beam-column joint without steel fiber has better ductility and stiffness than precast beam-column joint with steel fiber. However, precast beam-column joint with steel fiber has better energy dissipation and fewer cracks at corbel as compared to precast beam-column joint without steel fiber.

Reversed Loading

Based on the need of housing industrialization, using full-scale models, this paper investigated the seismic behavior of pre-cast concrete beam-column subassemblies with cast-in-situ monolithic joints under low-cycle reversed loading. The failure pattern, hysteretic characteristic, skeleton curve, ductility and energy dissipation were also analyzed. The result indicated that beam-column joints with longitudinal bars welded at the bottom of beams can meet the requirements of “strong column-weak beam, stronger joint”.
