Abstract:: In this paper we firstly introduce the characteristics of the Chuandou-type structure in detail,in order to help further understand the seismic capacity of the Chuandou-type timber frame.Based on the field investigation of towns and villages in Qianxinan and Qiannan prefecture of Guizhou province,we classified the architectural characteristics and structural characteristics of the Chuandou-type timber frame.According to the field survey in the disaster areas of the 2021 Luxian M_S6.0 earthquake and the 2022 Luding M_S6.8 earthquake in Sichuan,and the seismic damage data of the typical earthquakes(M_S≥6.0)in southwest China since 2013,the typical earthquake damage to the roof,wall,wood frame,etc.of the Chuandou-type timber frame is summarized.Finally,the causes of damage to the Chuandou-type timber frame are analyzed.The results show that it’s unique tenon-mortise connection ensures the good seismic performance of the Chuandou-type timber frame when It’s hit by earthquakes.Yet the seismic performance of the Chuandou-type timber frame’s infilled walls is relatively poor.
