摘要
土木工程结构风场实测结果是掌握结构风荷载作用机理和结构动力响应及破坏机理最直接的资料,也是修正现有试验方法和理论模型最为权威的依据。简要回顾了具有高柔低阻尼特性的高层建筑和高耸结构、大跨度桥梁和大跨空间结构的发展,分析了土木工程风场实测对于结构抗风设计的重要意义。对土木工程风场实测及实测新技术的研究进展进行了综述,提出了无线传感网络用于土木工程风场实测需要解决的关键技术问题。
The results of wind-field full-scale measurements in civil engineering structures are the directest information to afford insight into wind load effects,dynamic response,and breakage on structures.Likewise,they are the most authoritative bases used for revising present test methods and theoretical models.The development of civil engineering structures,such as tall buildings,high-rise towers,long-span bridges,and long-span spatial structures with higher flexible and lower damping are briefly reviewed here.Wind-field full-scale measurements are attached importance to for design of wind resistant structures.Subsequently,developments in wind-field full-scale measurements and new measuring techniques are summarized.Especially,for the purpose of practical applications of wireless sensor network(WSN) in wind-field full-scale measurements,the key technical issues to be resolved are proposed.
