When typhoons strike coastal cities, conventional buildings face severe challenges. The fabric membrane structure project—Starry Sky ETFE Air Cushion Membrane Bar—constructed by Yexing Membrane Structure Company, demonstrates how it not only “survives” but also exhibits exceptional architectural resilience and safety in extreme weather, thanks to its advanced ETFE membrane structure and air cushion system.
ETFE Air Cushion Membrane Structure: Far More Than Ordinary “Architectural Fabric”
Many wonder how such a lightweight membrane structure can withstand storms and heavy rain. The core secret of the Haikou Starry Sky Bar lies in its high-performance ETFE membrane material and intelligent air cushion system. This is far from a simple piece of “fabric”—it is an innovative architectural system integrating materials science and structural engineering.
What is an ETFE Air Cushion Membrane Structure?
ETFE (ethylene tetrafluoroethylene copolymer) is a lightweight, high-strength transparent fluoroplastic membrane material with a service life of over 25 years. The Haikou Starry Sky Bar processes it into multi-layer “air cushions,” which are continuously inflated to form a stable pneumatic dome. This structure is not only extremely lightweight (only 1% the weight of glass) but also far exceeds traditional building materials in tear resistance and self-cleaning properties.
How Does the Air Cushion System Work?
The bar’s dome is composed of multiple independent ETFE air cushion units. Each cushion is equipped with an intelligent air pressure monitoring system that continuously adjusts internal pressure. Like an inflated cushion, this process forms a high-strength curved surface on the structure, effectively distributing wind loads and snow/rain pressure evenly. This serves as the key technical safeguard enabling the structure to withstand typhoon weather conditions.
Performance in Action: The Haikou Typhoon Season Test
Located on the coast, Haikou faces the challenges of tropical storms and typhoons every year. Since its completion, the Starry Sky Bar has weathered multiple severe weather events, and its performance can be called a model for membrane structure architecture.
Wind Resistance and Structural Stability
Under strong winds, traditional roofs experience significant uplift forces. In contrast, the streamlined design and dynamic air pressure adjustment capability of the ETFE air cushion membrane allow wind to flow smoothly over the surface, greatly reducing wind resistance. Its flexible structure absorbs energy through minimal deformation rather than rigid opposition, ensuring overall stability. The design strictly adheres to the wind load standards for buildings in the Hainan region, with an extremely high safety factor.
Waterproofing and Drainage Design
The heavy rainfall accompanying typhoons poses another major challenge for buildings. The welding process of the ETFE air cushions ensures absolute airtightness and watertightness at the seams. Meanwhile, the precisely calculated double-curved shape of the dome guides rainwater to slide off quickly, working in tandem with the concealed drainage system around it to eliminate any risk of water accumulation.
Beyond Survival: A Unique Experience in Severe Weather
The ETFE air cushion membrane structure of the Haikou Starry Sky Bar is not just about “surviving” but about delivering an extraordinary experience in any weather.
Immersive Ambiance During Typhoons
Imagine listening to the rain and watching the changing skies under a safe, sturdy transparent dome, completely sheltered from the storm. This immersive experience of dancing with nature is the unique charm of membrane structure bar design, making it Haikou’s one-of-a-kind storm-viewing landmark.
Sustainability and Energy Efficiency Advantages
The high light transmittance of ETFE membrane material (up to 95%) significantly reduces daytime lighting energy consumption. Its thermal insulation and UV protection capabilities also provide a comfortable microclimate for the interior space, reflecting the principles of green building and sustainable design.
The Haikou Starry Sky ETFE Air Cushion Membrane Bar redefines the relationship between architecture and nature through technology. It proves that the most advanced building fabrics and structural systems can not only calmly withstand the challenges of typhoon weather but also transform these challenges into charm, creating a sturdy, safe, and imaginative space. This is not just Haikou’s cutting-edge bar but also a vivid preview of future adaptive architecture.
