Abstract:In response to the needs of seismic reinforcement and performance improvement of the mortise-tenon joint in Chinese ancient buildings, this paper proposes the use of embedded dampers to enhance the performance of the mortise-tenon joint and made five groups of scaled mortise-tenon joint models including unreinforced, single-layer reinforced embedded dampers and double-layer reinforced embedded dampers. Through the test research of seismic performance, the seismic performance of the mortise-tenon joints with different thickness and number of layers was compared with that of the joints without reinforcement, and the seismic performance of embedded dampers with different parameters on the joints of mortise-tenon was analyzed. The results show that the embedded dampers has the characteristics of two-way energy dissipation, multi-point yielding, and strong designability, which can greatly improve the seismic performance of the mortise-tenon joint and effectively suppress the joint phenomenon; the steel plate thickness and the number of layers of the embedded dampers are the main factors affecting the seismic performance of the mortise-tenon joint, and the thickness has the greatest impact on the mechanical properties of the mortise-tenon joint strengthened by the embedded dampers; the double-layer embedded dampers is more effective than the single-layer energy dissipator.
