A symmetrical mixed-grade composition glulam was fabricated using Japanese cedar plantation timber in the study. The sizes of the beam and column members were 120×304×1500 and 120×152×900 mm, respectively. A beam-column structure was constructed with 2 different types of developed metal connectors with different numbers of bolts to examine the shear resistance performance of the joints. The results indicated that the maximum shear capacity, yield strength, and energy absorption of a glulam joint using a 5-mm-thick flat-type connector were 34, 48, and 111% higher than those using a T-type connector. The structural characteristic factor also showed adequate ductility. The initial stiffness levels of glulam joints fixed with 3 and 5 bolts, respectively, were 2.8-and 4.0-times that with 2 bolts, while the energy absorption was reduced to 44 and 15%. Furthermore, joints fixed with 2 or 3 bolts had higher ductility factors and adequate structural characteristic factors for resisting a shear load.
