摘要:

从悬臂梁振动理论出发,讨论了高层建筑风响应的计算以及在风洞中利用高频天平测量高层建筑风荷载的原理,并进一步分析讨论了沿建筑物高度分布的平均风力、脉动风力、风致振动惯性力以及建筑结构设计所需要的等效静态风荷载的确定问题,指出了所提方法的局限性和应用范围,可为高层建筑结构设计中的风荷载确定提供参考.分析结果表明,求沿高层建筑高度分布的等效静态风荷载的方法适用于顺风向风力,在应用于横风向风力时由于涡脱落力的影响有理论误差.

Abstract:

Starting from the vibration theory of cantilever beams, the calculation of wind response of high-rise buildings and the principle of measuring wind loads of high-rise buildings by using high-frequency balances in wind tunnels are discussed, and the determination of average wind force, pulsating wind, wind-induced vibration inertial force and equivalent static wind load required for building structure design is further analyzed and discussed, and the limitations and application scope of the proposed method are pointed out, which can provide reference for wind load determination in the structural design of high-rise buildings. The analysis results show that the method of finding the equivalent static wind load along the height distribution of high-rise buildings is suitable for downwind force, and there is a theoretical error due to the influence of vortex shedding force when applied to crosswind wind.
