Outline
In this paper, it is proposed that the frame structure of glulam pillar and steel beam can address the issues of complex joint structure, limited beam stiffness and low lateral stiffness of long span glulam beam and column structure joints. Three joint specimens without planted bar and three joint specimens with the diameter of planting reinforcement as a variable were designed. Monotonic loading experiment were conducted on two joint specimens without reinforcement, while other joint specimens underwent low-cycle repeated loading to obtain their seismic performance, including failure mode, hysteresis curve, skeleton curve and energy dissipation capacity. The experimental results show that the measure of reinforced with planted bar can effectively improve the local bearing capacity of the transverse grain, the flexural stiffness and ultimate bearing capacity of the joints, but the increase in the diameter of the reinforcing bar has little impact. The energy dissipation capacity of the joint can be significantly improved by the measure of reinforced with planted bar, and the seismic performance of the joint can be improved. The failure modes of flexible end plate and rigid end plate are different, the members of the flexible end plates are S-shaped deformation and failure mode, the joint angle deformation is large, the bending stiffness is small, and the rigid end plate members are the transverse compression deformation and failure of the wooden column, and the bending stiffness and bearing capacity of the joint are strong. The formulas for the ultimate flexural bearing capacity of the joints are derived, and the theoretical values agree well with the measured ones.
