Abstract

In order to study wind-induced response characteristics of complex multi-span lattice frame, through comparing advantages and disadvantages of main aeroelastic model making methods, taking a typical 1 000 kV two-span substation frame as the background, the aeroelastic model satisfying the first 4 orders frequencies’ similarity ratios was designed and made by using the method of rigid segments and V-shaped spring sheets. Then, displacement and acceleration time histories at positions of typical parts of the structure under different wind speeds and wind directions were measured through wind tunnel tests of the aeroelastic model. Wind-induced response characteristics of the multi-span lattice frame were studied. Finally,
gust response factors of typical segments were evaluated by using the inertial wind load method and the gust load factor method. The results showed that the aeroelastic model designed using the method of rigid segments and V-type spring sheets can better satisfy similarity relations of important parameters, such as, shape, mass, frequency and damping ratio; effects of wind direction on the mean displacement are very significant, and the most unfavorable wind direction is at 15 ° to the corresponding principal axis; root mean square of acceleration responses in along-wind direction and cross-wind direction are in the same order of magnitude, and the wind-induced response in crosswind direction is obvious; the wind-induced response of the structure perpendicular to the central tower of span direction is dominated by the resonance component of the first-order mode, and resonance components of the fundamental order mode and higher-order modes of the side tower are all larger, contributions of higher-order modes can’t be ignored;
gust response factor of displacement is slightly larger than that of inertial force of the same segment; the test results can provide a reference for anti-wind design of multi-span lattice frames.
