摘要：
The calculation formulas for lateral galloping critical wind speed and amplitude of prisms with wind attack angle were deduced with the quasi-steady theory. H-shaped columns were adopted to conduct wind tunnel tests and calculations. The results showed that the galloping critical wind speed calculation results using the proposed method are very close to those using Den-Hartog formula under smaller wind attack angles; under larger wind attack angles, the difference between the two results is bigger, so Den-Hartog formula can't be used to do galloping calculation under larger wind attack angles; the results of theoretical calculation for galloping amplitude agree well with those of tests, the correctness of the proposed method is verified. © 2018, Editorial Office of Journal of Vibration and Shock.
