An experimental investigation was undertaken into the strength and deformation behavior of two types of precast reinforced concrete beam-to-column connections. Referred to in this paper as Types A and B, these connections are recommended by the PC/ Committee on Connection Details and the Australian Prestressed Concrete Group for use in precast reinforced concrete building frames. A total of 18 halfscale interior connection models were designed, built, and tested to failure to evaluate their strength and ductility properties under static and unidirectional repeated loading. The comparative study hows that the two types of precast concrete connections performed satisfactorily in that their bending strengths are, without exception, higher than the monolithic connections. In addition, the ductility and energy absorbing capacities of the precast connections, generally, are superior to their monolithic counterparts.
