The authors have presented a prediction method of fluctuating wind force with no static component induced an elasto-plastic response based on an energy balance, and shown its validity. However, the method was limited to the case of a narrow-band random process. This paper presents a prediction method expanded to the case of wide-band random process. A prediction method for a mean wind force induced response is also presented. The authors show that wide band flactuating wind force induced elasto-plastic response is determined by not only energy balance for resonance component but also equilibrium of force between a quasi-static component of wide-band fluctuating wind force and an elast-plastic system. The agreement between the predicted value and results of time-history analysis was finally confirmed.
