本文将风荷载分为两部分，即由风的稳定分量引起的静风荷载和由阵风的垂直和水平分量引起的脉动风荷载，用平稳时间序列的统计概念确定脉动风荷载的响应，并提出了估算响应所需的风结构相关数据。以3300 ft悬索桥为例，分析了垂直风和水平风对悬索桥动力特性的影响。
Loading of aerodynamically stable suspension bridge by storm winds is considered in 2 parts, viz, static wind loading due to steady component of wind and fluctuating loading due to vertical and horizontal components of gustiness; response to fluctuating loads is determined using statistical concepts of stationary time series; pertinent data on wind structure required in estimating response are suggested; 3300 ft span suspension bridge is analyzed as example; dynamic effects of vertical and horizontal gusts are highly significant.
