摘　　要：为研究大跨度连廊结构在风载荷作用下的影响,应用ADINA有限元分析软件对大跨度连廊结构进行流体—结构耦合的数值模拟计算不同风速大小、不同风向角作用下分析结构,流场的位移应力.得到结构体沿高度变化的位移,结构表面应力分布及流场应力分布和速度矢量.结果表明:在风载荷作用下,结构位移最大出现在结构中心以下位置.结构表面压应力分布状态与载荷大小无关,结构迎风面压力为正值,背面压力为负.软件的分析有利于更好地认识到流固耦合作用对结构体的影响.In order to study the influence of large-span corridor structure under wind load, large-span corridor structure fluid - structure coupling numerical simulation was conducted by using the finite element analysis software ADINA, and the structure and flow field of the displacement stress was calculated under different wind speed and wind direction angle. Displacement of the structure along the height change and surface stress distribution of the structure, stress distribution of flow field and velocity vector were gained. The results show that under the wind load, structural maximum displacement was under the center of the structure position. Structure surface compressive stress distribution and load was independent of the size, and structure of windward pressure is positive and negative pressure on the back. Using software analysis is better to realize the fluid-structure coupling effect on the structure.
