The investigation into the wind-environment of bridge on complex terrain involves these factors, such as geometry of structure, plane position, height, direction of inflow, surrounding terrain, upstream landform etc. Being lack of the research reserves, the designer can't accurately forecast the wind-induced response of the structure on the complex terrain. And the most effective way of the wind characteristics...
Taking the Xiangjiaba-Shanghai special high-voltage DC??800kV transmission line project being constructed as an example, based on the basic characteristics of fluctuating wind and Kaimal spectra, considering various influences such as structural style of long span transmission tower,characteristics of power spectral energy i.e,the improved weighted amplitude wave superposition (WAWS) method adopting...
A method for analyzing wind-induced vibrations of 1000kv Hanjiang ultrahigh voltage long span power transmission towers coupled with power lines is discussed in this paper. This paper also discusses the influence on response characteristics of differences in transmission support systems and differences between peak factors, computed from a time-series and from power spectrum density. Through the analysis...
