In order to study the wind vibration performance of Chinese early traditional timber structure, the main hall of Tianning Temple in Jinhua of Zhejiang province was taken as an example. Firstly, based on the precise geometric information acquired by 3D laser scanning, the calculation model of the main hall was built by the finite element software of SAP2000, and its dynamic characteristics were analyzed. Then, the time history curves of fluctuating wind speed and fluctuating wind pressure based on AR model was generated by the software of MATLAB. The generated wind pressure was applied to the FEM model and analyzed. The results show that the top ten natural frequencies of this structureare among 3.617 Hz～18.672 Hz. The wind vibration response of this structure is mainly influenced by the top four natural modes. The wind vibration coefficients obtained by the time history analysis of wind pressure are 1.1~1.5 times of the wind vibration coefficients calculated according to the Chinese current load code. These results can provide a reference for analysis of wind vibration performance of Chinese early traditional timber structure.
