Abstract：Rigid models were designed based on Taishan nuclear power plant to investigate wind pressure distribution and wind-induced dynamic response of main powerhouse structure of conventional island in a third generation nuclear power plant. Fluctuating wind pressure was tested under the turbulent flow in a boundary layer wind tunnel considering the interference effects of neighboring nuclear island and adjacent structure. The characteristics of mean, fluctuating and peak pressure coefficients on the structure were analyzed. A calculation procedure was developed for evaluating the wind-induced dynamic response by using frequency-domain method. The equivalent static wind loads and wind load factor were obtained based on optimization theory and the critical wind angles were determined. The calculation and analysis above can supply a reliable guide for safety evaluation of wind resistance.
