In the precast concrete moment resisting frame, the U-shaped beam shell and the column are constructed with precast concrete. The beam core and the beam-column connection are monolithically constructed with cast-in-place concrete. The test specimens were a cruciform sub-assemblage of the beam, column, and their connection. Five precast concrete specimens and one conventional monolithic specimen were tested for cyclic loading. The parameters for this test were the reinforcement detail for the precast beam shell, stirrup spacing in the beams, and length of the beam shell seated on the column. Based on the test results, the strength, stiffness, energy dissipation capacity, and deformation capacity were evaluated. The test results showed that regardless of the test parameters, the beam-column connections showed good strength and deformation capacity. However, due to bond-slip of the reinforcing bars located inside the precast concrete U shell, the energy dissipation capacity decreased. Because of the shear area of the connection, which was decreased by the beam shell seating on the column, the shear crack and shear deformation of the beam-column connection were increased.
