摘　　要：采用ADINA有限元软件对某大跨度栈桥结构进行了流体-结构耦合数值模拟计算,得出该类结构的风致动力响应特性。研究了流场速度、压力,结构的位移、等效应力以及风振系数和风压分布系数。A long-span conveyor gallery structure model with fluid-structure interaction（FSI） is introduced to investigate the wind-induced dynamic response using ADINA in this paper.The velocity and the pressure in the flow domain and typical features of the structure such as displacement and equivalent stress are observed.Furthermore,the wind-induced dynamic coefficients and the wind pressure distribution coefficients are investigated.
