Abstract:: Based on field investigation of the residential houses in Dali and Lijiang of Yunnan province,we analyze the difference of the tenon structure of the column-and-tie timber structures between the two places.In order to study the seismic performance and stress characteristics of the timber structure in the two places,we use the finite element analysis software to simulate the low-cycle reciprocating load to the gable-shaped frame of the column-and-tie timber structure in the two places.The results show that the gable-shaped frame in Lijiang has better seismic performance than that in Dali.The tenon joint of the transverse member and the longitudinal member is the weak part of the timber structure in both Dali and Lijiang,the end tenon is the weak part of the tenon joint.The gable-shaped frame in both Dali and Lijiang have low lateral stiffness,and they are apt to tilt under the lateral load.
