浅议高层建筑抗风的技术问题及对策

Technical Problems and Countermeasures on Wind-Resistant Design of High-Rise Building

高层建筑横风向、扭转向风荷载及群体建筑干扰效应可能引起较大的风致响应。本文综合分析了高层建筑受风荷载的特点,对不同的抗风要求提出了针对性的抗风措施。研究和工程实例表明,通过改变建筑外形或结构动力特性可有效改善高层建筑受风环境,从而降低建筑风致响应。

Across wind load,torsional wind load and interference effect from next buildings may induce great responses on high-rise buildings. The paper introduced characters of wind loads on high-rise buildings, and countermeasures are recommended according to control responses. Research and result of project case showed that modification of building shape and dynamic property were effective methods to improve wind environment and decease wind induced responses of high-rise buildings.
