ABSTRACT
Chinese traditional timber buildings, developing from origin to mature, experienced thousands of years and vicissitudes of this oriental civilized country. These ancient buildings need to be preserved well by us, but it is common to find the damage of Chinese traditional timber buildings under strong wind action. The wind resistant characteristic of traditional hall-style timber structure in the south Yangtze river regions was studied, exemplified by the main hall of Baoguo Temple in Ningbo, Zhejiang province, which is the oldest buddhist timber structure in the south Yangtze river regions. The characteristic of fluctuating wind speed can be described by power spectrum and correlation function. Through the comparative analysis of the wind vibration coefficients obtained by time history analysis and the wind vibration coefficients calculated according to the Code, the wind vibration coefficients calculated according to the Code decrease with the decrease of the building height.
