BYD Shaoxing Shengzhou Racing Circuit: Steel Membrane Structure Observation Deck

The design of BYD Shaoxing Shengzhou Race Track ingeniously blends two major elements: high-speed racing and natural landscapes. Among them, the dry sand dune viewing platform serves as the core landmark of the track, perfectly achieving a triple balance of functional utility, visual identification, and ecological protection. The creative design of this platform originates from the shape of sand waves and aerodynamic trajectories generated by racecars during high-speed driving. Architects have crafted a streamline curved surface that resembles the rhythm of sand dunes through a robust steel structure framework and a lightweight membrane structure skin. This not only vividly interprets the thrilling speed of racing but also constructs a comfortable viewing space for on-site spectators that provides both sunshade awning and rain protection functions. 

The top membrane structure collaborates closely with the steel structure to form a stable force system. The membrane structure's skin: a balance of lightness and tension. The top is made of high-strength PTFE membrane material, which takes into account both light transmittance and wind resistance. The membrane units are designed in different areas: the track side uses a matte silver coating to reduce glare that could interfere with the drivers; the viewing side is made of a translucent gradient membrane that filters ultraviolet light. The boundary between the membrane and the steel structure is connected by custom aluminum alloy clamps, achieving a visual tension that is 'soft with a hint of rigidity'.

During the construction process,  Wanhao Group fully leveraged its technical advantages, employing advanced construction techniques and equipment to ensure high-quality advancement at every stage. Faced with a complex construction environmental architecture, the team overcame multiple technical challenges by continuously optimizing the construction plan.

This observation platform that integrates aerodynamics and materials science is not only a showcase of racing culture but also interprets the symbiotic relationship between "speed and structure" through engineering technology innovation. Its successful practice provides important technical references for large-scale curved buildings, marking a new breakthrough in the field of complex environmental adaptability for Chinese steel structure architecture .
