RESEARCH PROGRESS ON SEISMIC PERFORMANCE OF MORTISE-AND-TENON JOINTS IN TIMBER STRUCTURES
Mortise-and-tenon joints exhibit typical semi-rigid connection characteristics,which are crucial for the seismic performance of the overall structure.This review summarizes the current research on mortise-and-tenon joints from two perspectives:hysteresis curves and fitted restoring force models.Regarding hysteresis curves,it dis-cusses the load characteristics and failure modes of both straight and dovetail joints,noting that the hysteresis curves generally display a'Z'-shaped pattern with a distinct'pinching'effect based on low-cycle repeated load tests.In terms of restoring force models,it summarizes the trends observed during loading and introduces the four-parameter power function model.This model effectively captures the variation in joint stiffness for different joint sizes and pro-vides a more accurate representation of structural seismic performance.The review reveals that a unified calculation method for the seismic performance of mortise-and-tenon joints is lacking,and challenges remain in achieving 100%restoration of damaged joints.
