Wind hazard damage estimation was addressed for light steel industrial buildings which were the typical wind vulnerable structures in southeast coastal cities. With parametric analysis of wind damage and the structural failure features

the envelop elements and the connecting elements were determined as the pivots of the damage analysis. Upon the consideration of the coeffect of exterior wind pressure

windinduced internal pressure and windborne debris damage

a typhoon load model was proposed. And with the calculation method of the element resistance from the regulation

the procedure of the damage estimation was described and the damage classification of industrial buildings was specified with detailed indicators. Finally

the proposed method was approved with the actual data of typhoon CHANCHU (0601).
