To investigate the mechanical behavior of column transfer structures enhanced by ceramic composite materials, thecharacteristics of the mountain shaped retreating terrace style lapping column transfer structure in a certain museum inHangzhou, one of the three-layer and three-bay lapping column was taken as the main research object. Static and quasistatictests were carried out respectively on 1:5 scale model specimens, and the static and quasi-static characteristics of themountain-shaped retreating terrace style lapping column transfer structure were analyzed. Finite element simulations werealso conducted to validate experimental observations. Results showed that under 1.2 times the design vertical load, thespecimen remained in the elastic range with no visible cracking, indicating excellent load-bearing capacity. Furthermore,the inclusion of ceramic materials significantly improved the hysteretic behavior and energy dissipation performance of thejoint under cyclic lateral loading. The peak inter-story drift ratio reached 1/28 without structural failure, meeting seismicperformance requirements. This study provides useful insights into the integration of ceramic-based composites in complexstructural transfer systems for improved resilience.s
