大跨结构是典型的风敏感结构,风荷载和风致振动常常是控制结构安全性的主要因素.本文系统回顾了国内外大跨结构抗风研究领域的进展,主要涉及风洞试验、大跨结构气动弹性模型、风振系数、等效静风荷载、风致响应等方面,并对存在的不足以及进一步研究的方向提出建议.
The long-span structures are typical wind-sensitive structures. The wind loads and the wind-induced vibration are usually the major factors which control the security of structures. The development of wind resistance studies on long-pan structures, both nationally and internationally, is systematically reviewed in the paper, which mainly includes wind tunnel tests, long-span structure aeroelastic model, wind vibration coefficient, equivalent static wind load and wind-induced analysis. The suggestion on further studies and present deficiency are given out at last.
