“…Wind engineering research methods include theoretical analysis (Shiotani and Iwatani, 1980;Solari, 1983;Davenport, 1967;Balendra et al, 1989), field measurement, and wind tunnel testing. Wind tunnel tests, widely used in long-span space structures and high-rise structures, include the model multi-point synchronous pressure test (Zou, 2013), the aero-elastic model test (Wang, 2011), and the high-frequency force balance (HFFB) test (Bernardini et al, 2013). The HFFB test allows calculating the wind-induced response of a structure by measuring the bending moment and force on the model under a wind load by using a highly sensitive balance installed at the bottom.…”

In order to propose a complete, wind-resistant design method for ultra-high voltage (UHV) transformer frames, the wind-induced vibration characteristics of a 1 000 kV transformer frame (TF1000) were studied using a high-frequency force balance (HFFB) test. Five section models and one whole model of the TF1000 were designed and constructed using 3D printing, and these were evaluated in a wind tunnel by means of HFFB tests for multiple loading scenarios. The finite element method (FEM) was used on the test data to analyze the wind-induced vibration on the TF1000. The results demonstrate that the shape factor of the TF1000 is significantly affected by the flow field type and solidity ratio; the minimum value occurs when the wind direction is between 30 and 45°. Moreover, all the shape factor values obtained by the test are larger than those established by the Chinese code. The wind-induced vibration analysis indicates that the most unfavorable wind direction for the TF1000 is approximately 60°, with a wind-induced vibration coefficient between 1,7 and 3,9.

“…Therefore, it is necessary to fully understand wind pressure and the distribution of light-steel structure roof. So far, research methods for wind load mainly include field measurement, wind tunnel test [2] and numerical simulation. As computer software and hardware level and computational fluid mechanics rapidly develop in the last two decades, numerical simulation techniques have been playing an increasingly important role in the research of structural wind engineering field with distinct advantages.…”
