Characteristics of wind induced vibration of a historical wooden pagoda were investigated by a wind tunnel test. The 1/40 structural model of 5 stories pagoda was used for the aerodynamic wind tunnel test, which simulate a non-linear characteristics of load-deformation relationship. It was found that the along-wind response is much larger than the across-wind response in this type of pagoda. The along-wind displacement increases rapidly when the wind speed is larger than the critical value. When the wind speed is beyond the critical value, the period is very unstable, which can be successfully analyzed by the multi-resolution analysis of a wavelet decomposition.
