摘　　要：大跨斜拉网格结构是网格结构、塔住和拉索组合的刚柔体系,有广泛的应用前景。风激动力响应是其设 计计算中的一个关键问题。大跨斜拉网格结构在风荷载的作用下具有非线性特征,其风激响应是复杂的耦合响应。大 跨斜拉网格结构风载响应研究是亟需解决的问题。在介绍风荷载特性、风对结构作用和风荷载模拟技术基础上,阐述了 结构风工程中大跨斜拉网格结构研究的状况,展望该领域研究的前景。The long span cable-stayed reticulated structure(CSRS)is a kind of hybrid structural system composed of fiexible cables,towers and spatial reticulated structure .Wind-induced dynamic response is one of the key problems in calculation and design of CSRS. The property of wind-loading,wind simulation technique and the interaction between wind and structures are reviewed. The researchs on wind-induced dynamic response analysis of long span cable-stayed reticulated structure are summerized and the prospect problems needed to be solved in wind engineering for this kind of structures.
