On Wind-Induced Vibration Respons of Tall Building with Wind-Structure Interaction

In order to reveal the structural dynamic characteristics in natural wind, multi-dimensional random wind load of tall building is simulated by using harmonic wave superposition method. Then the coupling dynamical equations of structural system are solved by using Wilson- integration method considering the coupling effect of wind-induced interaction. Based on the analysis, it is clear that the coupling of wind-structure is equivalent to the damping effect and the dynamic response of the structure has decreased, when taking the wind-structure interaction.
