Abstract
In this paper, the wind-induced response of Jiayuguan wooden building (world cultural heritage) in Northwest
China was studied. ANSYS finite element software was used to establish four kinds of building models under different working
conditions and carry out modal analysis. The simulation results were compared with the field dynamic test results, obtaining the
model which reflects the real vibration characteristics of the wooden tower. Time history data of fluctuating wind speed was
obtained by MATLAB programming. Time domain method and ANSYS were used to analyze the wind-induced vibration
response time history of Jiayuguan wooden building, obtaining the displacement time history curve of the structure. It was
suggested that the wind-induced vibration coefficient of Jiayuguan wooden building is 1.76. Through analysis of the
performance of the building under equivalent static wind load, the maximum displacement occurs in the three-story wall, gold
column and the whole roof area, and the maximum displacement of the building is 5.39 cm. The ratio of the maximum stress
value to the allowable value of wood tensile strength is 45 %. The research results can provide reference for the wind resistant
design and protection of ancient buildings with similar structure to Jiayuguan wooden tower.
