Abstract
This paper discusses structural behaviour of hybrid precast concrete column under static loading. Comparison between the hybrids precast concrete and ordinary cast in-situ concrete columns are also discussed. The column and sandwich concrete beam connection were tested represent typical construction of conventional housing. Experimental investigation was conducted on 5 hybrid concrete column and 6beam-column connection to evaluate the load- displacement characteristic, failure mode, and moment capacity. Test results showed that the ratios of experimental moment capacity to the theoretical one were1.27and 1.68 for 40 mm and 60 mm eccentric loads respectively. The results indicated that the moment capacity under eccentric load can be accurately estimated using the theoretical formula. However, under concentric load the coefficient of 0.67 should be added. It has also been found that the additional anchor to the shear reinforcement of the beam gave a significant increase of the load bearing capacity of the beam.
