Abstract: This study focuses on the overall performance of traditional wooden dwellings in Dali Bai area. Two commonly used wooden frame structures in Dali Bai dwellings were selected as research objects， and the ANSYS finite element numerical simulation method was used to establish a structural overall model. The deformation and stress characteristics of two wooden frame structures under static load were analyzed， and the displacement and acceleration responses of the two wooden frame structures under earthquake loads were obtained through time history analysis. The results showed that under load， the peak deformation of the two wooden frames was within the allowable range，and the compressive， bending and shear bearing capacities of the components all met the requirements. According to the modal analysis， the longitudinal stiffness of the wooden frame was weak， and the transverse stiffness was slightly greater than the longitudinal stiffness， which conformed to the general vibration sequence of the structure. On the basis of modal analysis， the dynamic response analysis of wooden frame was carried out， obtained a comparison between two types of wooden frames， the dynamic amplification factors of each node of the two wooden frames did not show significant differences. The peak displacement and acceleration response did not appear at the same time， and there was a certain phase difference. In conclusion， the two types of Dali Bai traditional wooden frame structures are basically intact and currently in a safe state.
