Abstract
The displacement and comfort of the tower top are important reference indexes for wind resistance design of the curved torsional column spiral beam landscape tower (LT). The dynamic response of tower top and platform is analyzed and discussed through wind tunnel test of aeroelastic model, and the influence of the tower itself on wind response and comfort of pedestrian is studied. The conclusion shows that the wind Angle has a great influence on the displacement of the top of the landscape tower, and the 150° wind Angle is the most unfavorable wind Angle of LT displacement. In addition, the peak acceleration of the platform reaches its maximum value at 90° wind Angle, resulting in poor lateral pedestrian comfort at high wind speed. It is suggested to restrict pedestrians from climbing the tower at high wind speed or to carry out vibration reduction research on such structures at high wind speed.
