The wind pressure on a building is intricately fluctuating with wind turbulence and vortex shedding. It is important to understand the characteristics of the pressure fluctuation for understanding the wind forces on a building. The POD ( Proper Orthogonal Decomposition ) analysis is known as a method of understanding multi-point fluctuation data. Already, the method is applied to the wind pressure of acting on a low-rise building or a square tall building. In this paper, the complexed POD analysis (variance matrix are expressed by complex number) are applied to the fluctuating pressure of an tall building. The other hand, the contribution of local pressure to the wind force of the whole model is calculated by the LRC ( Load Response Correlation) method.
