“…To accurately identify the vibration parameters of long-span transmission towers, many scholars have carried out relevant tests and studies through actual measurement [1][2][3][4][5]. Zhang Jiayi et al analyzed the dynamic characteristics and wind-induced response and evaluated the wind-resistant performance of typical angle steel transmission towers on the newly built 220kV dual-circuit line in the coastal area of Fuding, Fujian Province.…”

In order to improve the rationality of vibration parameter values and lean design of long-span transmission tower, this paper carries out the field study on vibration characteristics of a long-span transmission tower with a 385 m height as the study object, in which the vibration parameters such as vibration frequency and mode shape of the crossover tower were studied. Results show that the vibration of the crossing tower is dominated by horizontal vibration, the vibration in the z direction is symmetrical, and the average vibration acceleration is approximately zero. The mode shapes of the crossover tower in the first three orders were first-order transverse bending, first-order longitudinal bending and first-order torsional modes. The corresponding frequencies were 0.58464Hz, 0.58705Hz and 0.81486Hz, respectively. In light of the measured data, the mode shape of the crossing tower calculated by the stochastic subspace identification method is in good agreement with the finite element simulation results.
