摘要
基于脉动风的基本理论和Davenport风荷载功率谱,提供了在频域内杆系结构迎风风激响应的计算方法。应用Morison方程确定风荷载,同杆系结构耦合求解其各阶振动的频率响应函数,并根据线性系统特性计算结构的位移谱。给出不同参数的杆式结构在各种风速作用下的位移图谱,可供工程应用参考。
Based on basic theory of pulsating wind and Davenport's power spectrum, a calculating method of head-wind wind-excited response for pole structures in frequency domain is presented. Wind loading is determined by Morison equation, the frequency response function of vibration of each-order is calculated considering the coupling between wind loading and pole structure, and displacement spectrum is obtained according to the characteristic of linear transformation system.
