Review on mechanical performance of mortise-tenon joints in traditional timber structures
The mortise-tenon joint is a crucial component that distinguishes traditional timber structures from others.It exhibits characteristic semi-rigid behavior which significantly affects the seismic performance of traditional timber structures.In this article,the characteristics and applications of mortise-tenon joints in different member connections were reviewed,and the research status on the mechanical performance of mortise-tenon joints was also discussed,focusing on the force mechanism,mechanical models,and numerical analysis.The load characteristics,failure features,and influencing factors of different joint types were examined.The establishments of theoretical analyses,tests,and numerical simulations were explained,along with the limitations of each method.Additionally,wood constitutive relationships and both refined and simplified numerical analysis techniques were discussed.The issues such as incomplete joint classification,inadequate consideration of factors,complex models,and insufficient simulation accuracy were identified in the research.These findings offer guidance for future research and the accurate assessment of the performance of mortise-tenon joint in traditional timber structures.
