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 MS6.0 earthquake and the 2022 Luding MS6.8 earthquake in Sichuan,and the seismic damage data of the typical earthquakes(MS≥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.
