Abstract: The main torch structure of the Beijing 2022 Olympic Winter Games is a typical stage-shaped structure with a large area of thin walls, being extremely sensitive to wind loads. There are two typical states: inclined support and vertical suspension state in the ignition ceremony, respectively. Among them, the inclined support state needs to determine the wind load required for structural design, and the vertical suspension state needs to show the wind-induced vibration response of the main torch structure. Based on the measured data, the average wind speed profile and turbulence one around the National Stadium are respectively presented. Through the wind tunnel test of scale model wind environment and the probability distribution of local wind speed in February, the determined is the normal operating wind speed of the main flare structure both in inclined support state and in vertical suspension one. The shape coefficient is obtained by the force-measuring wind tunnel test of the main torch structure on the inclined support state and vertical suspension one. The random wind vibration response of the vertical suspension state is also developed, which provides a technical support for the smooth progress of the main torch structure in the ignition ceremony for the 2022 Winter Olympics in Beijing.
