In order to gain insight into the response characteristics of Ting Kau Bridge under turbulent wind, the time domain approach which considered the time-space correlation of fluctuating wind velocities and inter/multi-mode contributions of the bridge structure, was utilized. The fluctuating wind velocity field along the bridge axis was generated with a modified spectral representation method. Self-excited wind forces are modeled using the quasisteady formulation in the frequency domain and then converted into the time domain. The Ting Kau Bridge was idealized as a three dimension frame model. The buffeting analysis of the bridge under gusty wind shows that there is no aerodynamic instabilities occurred due to selfexcited forces up to the mean wind speed of 70m/s and the bridge behaves well under the design wind speeds.
