Abstract

Square structures and components are widely used in engineering structures, and their wind-induced vibration problems become more prominent with the increase of height and span. Corner treatment is a commonly used aerodynamic measure in square section structural engineering. In order to investigate the effect of wing corner treatment on the wind induced vibration performance of square cylinders in all wind directions, wind tunnel tests were conducted on standard square cylinders and wing corner treated square cylinder in all wind direction section models. The Vortex-induced vibration and galloping performance of standard square cylinders and wing square cylinder in all wind directions were analyzed. The results showed that: 1) The corner treatment of the wing plate reduced the wind direction range of Vortex-induced vibration in the square cylinder, but the maximum amplitude of Vortex-induced vibration and the wind speed locking range were significantly larger than those of the standard square cylinder. The wing plate did not improve the Vortex-induced vibration performance of the square cylinder, but rather was not conducive to the Vortex-induced vibration of the square cylinder. 2) The treatment of wing plate corners did not increase the critical wind speed for galloping of the square cylinder, but reduced the wind direction angle conditions where galloping occurred. Overall, the treatment of wing plate corners did not improve the galloping performance of the square cylinder. 3) at all wind direction, Vortex-induced vibration and galloping coupled vibration as well as uncoupled vibration were observed in winged square cylinders, indicating that wind direction is an important factor in changing the type of galloping vibration of the cylinder.
