【 摘 要 】

This paper presents conceptual design and development of a new hybrid precast beam-to-column connection. The hybrid precast connection is made of steel connection which is embedded in concrete beam and column. The beam and column are connected to each other by bolts connectors. The performance connection is evaluated through the quasi-static test. To aid the aim, the monolithic connection and hybrid connection of the same beam and column size are modeled in 3-dimensions using ABAQUS commercial software. The results of the finite element analysis indicated that the hybrid connection was slightly stiffer than the monolithic connection while the ductility of both connections was similar. In addition, the failure mode of hybrid precast connection followed the strong-column weak-beam concept.
