Mortise-tenon joints are composed by mortise and tenon, and can be used for load bearing with preferable elastic characteristic and counteracting on lateralload.A model had been made according to the actual ancient wooden place with a 1:3.52 scale of the prototype structure, which was in accordance with the requirements for the shape and structure by Ying Zao Fa Shi (Building Standards)of the Song dynasty and mortise-tenon joints were utilized in the model. The shaking table test had been carried out on the model, the dynamic characteristics of frequency damping ratio and seismic response of the model before and after consolidation were measured and compared. Based on the good behavior of the mortise-tenon and its importance on the connection between various parts ofthe wooden structure, it has been realized that consolidation ofthe mortise-ten on joint is one of the effective methods for the seismic resistant strengthening of Chinese ancient timber building.
Keywords: Chinese historic buildings; timber structure; shaking table test; mortise-tenon joint
