风致飞射物研究进展及建议

Progress and Recommendations of Research on Windborne Debris

中国是受风灾影响较为显著的国家和地区之一,风灾不仅会造成工程结构损伤,甚至会导致结构的倒塌破坏。风致飞射物是强风作用下结构损伤、破坏而形成的一种高速运动碎片,其冲击作用对周边工程结构和人员的安全构成二次威胁,中外学者近年来针对风致飞射物开展了相关研究工作。基于此,从风致飞射物的形成机制、飞行特性、冲击作用3个方面阐述当前中外研究进展,并针对现有研究工作提出今后的研究建议和发展方向,为进一步深化风致飞射物及其防治工作研究提供借鉴。

China is one of the countries and regions significantly affected by wind damage,which can not only cause damage to engineering structures,but also lead to structural collapse.Windborne debris are a kind of high-speed motion debris formed by structural damage and destruction under strong wind,and their impact poses a secondary threat to the safety of the surrounding structures and personnel.Chinese and overseas scholars have carried out relevant research work on windborne debris in recent years.Based on this,the current domestic and foreign research progress was described from three aspects:formation mechanism,flight characteristics and impact effect of windborne debris.Future research suggestions and development directions were proposed,so as to provided reference for further deepening the research of windborne debris and their prevention and control work.
