The Guangzhou University Central Stadium, accommodating 40,000 spectators with a 33,673 m² area, showcases unique roof designs tailored to its landscape. Designed for a basic wind pressure of 0.6 Kpa (112 km/h wind speed), the east and west stands feature distinct structures.  

The east stand is integrated into the hillside, with the architect’s concept of merging the stand into the mountain, creating a part of the hill. A green artificial turf-covered sandwich panel roof extends over the stadium, seamlessly blending with the landscape. The roof is supported by a suspension structure, transferring loads efficiently to the foundation.

The east stand, merging with a hillside, has a green artificial turf-covered sandwich panel roof (9500 m², 257 m span, 34 m cantilever). Using a suspension structure, it efficiently transfers load to the foundation.  

The west stand symbolizes "clouds over mountains" with a PTFE membrane roof (16,000 m², 300 m span, 60 m cantilever), supported by radial and circular trusses.

    Membrane materials have increasingly been used for building facades, offering a range of benefits such as fast installation, low construction costs, and effective surface coverage that enhances both aesthetics and signage. As a result, mesh membrane materials are commonly found in commercial centers, cultural hubs, exhibition halls, and sports venues.

     One popular option is the use of perforated mesh membrane, which features a wider spacing between base fibers and a partial coating, resulting in a certain perforation rate (20–70%). This material has high transparency (30-70%), allowing natural light to penetrate while maintaining excellent shading and decorative effects. Alternatively, semi-transparent membranes can be used for different applications, offering a balance of light diffusion and energy efficiency.

Project Case 1: Germany Pavilion at Expo 2010, Shanghai
    The Germany Pavilion at the 2010 Shanghai Expo covered an area of 6,000 m². The facade was constructed using high-strength PTFE membrane with a Ferrari metal silver coating and 28% perforation. Approximately 21,000 m² of membrane material was stretched over the pavilion’s roof and surrounding walls. This membrane effectively blocked up to 80% of sunlight radiation, significantly reducing the building’s cooling load while allowing natural light to enter. As a result, the pavilion's energy efficiency was greatly improved.

Project Case 2: Germany Pavilion at Expo 2015, Milan
    At the Milan Expo 2015, the Germany Pavilion also utilized membrane structures as a key material in its design. This highlighted the growing recognition and use of flexible textile technology in architectural design, demonstrating its adaptability and sustainability for global expos.

Project Case 3: Xinhe R&D Design Center
    The Xinhe R&D Design Center, with a total building area of 61,000 m², features a semi-transparent membrane facade that allows 40% of light to pass through. The PTFE membrane is installed at a distance from the building, reducing sunlight intensity and providing ventilation during hot seasons, while still allowing for natural light inside. This innovative facade design ensures both energy efficiency and comfort for office spaces.

The Foshan Century Lotus Sports Center, located in Foshan New City, Guangdong Province, was built for the 12th Guangdong Provincial Games and has become a landmark of the city. The center, designed by the German firm GMP, covers 42 hectares and includes a stadium and a swimming and diving hall. The stadium, named "Century Lotus" for its lotus-shaped design, features a membrane roof that is both striking and functional.

The roof, which was completed in 2006, spans 310 meters in diameter and is made of PVDF membrane material. The structure includes a double-ring design: an inner tensile ring made of steel cables and an outer compression ring supported by concrete-filled steel pipes. The roof is designed to withstand the high humidity and tropical climate of Foshan, which is characterized by hot and damp conditions. The membrane's excellent durability and UV resistance are essential for enduring the region's challenging weather, with wind speeds reaching up to 28m/s.

The membrane structure not only provides superior environmental resistance but also adds to the aesthetic appeal of the stadium, making it a recognizable symbol in Foshan. The roof's unique design allows for easy maintenance while offering optimal protection from the elements, contributing to the stadium’s long-lasting functionality and iconic status.

A tensile fabric structure is a lightweight architectural solution that relies on the balance of tension and compression. Unlike traditional buildings, it uses fabric materials like PVC, PTFE, and ETFE, supported by cables and steel frames, to create elegant, durable, and cost-effective shelters. These structures are widely used in stadiums, canopies, exhibition halls, and shade structures due to their unique aesthetic appeal and functional flexibility.

To ensure the stability and safety of these structures, load analysis is essential. This analysis evaluates the forces acting on the structure, such as wind load, snow load, live load, and temperature load, to prevent issues like sagging, tearing, or collapse.

Wind Load: Wind creates pressure that can push, pull, or lift the fabric. Proper design reduces wind resistance by shaping the fabric to deflect airflow. BDiR uses advanced software to simulate wind forces and ensure the stability of the structure.

Snow Load: In colder regions, snow accumulation can increase weight on the roof, leading to sagging or collapse. Proper slope design ensures snow slides off, while fabric tensioning increases load capacity.

Live Load: This refers to temporary loads like maintenance workers walking on the structure or hanging decorative items. Load capacity is built into the design to ensure the structure remains stable under such loads.

Temperature Load: Temperature changes cause fabric and metal components to expand or contract. BDiR selects materials with high thermal resistance and designs tension systems to adapt to these shifts, ensuring long-term stability.

Load Calculation: BDiR's engineers collect environmental data (wind speed, snow density, temperature) and apply load coefficients. Advanced software simulates forces, and adjustments are made to the fabric shape, pre-tension, and anchor points.

Custom Design: Each project is tailored to the site's unique climate conditions. BDiR’s designs feature optimal slope, fabric curvature, and reinforced anchor points to resist wind, snow, and live loads.

Material Selection: Using materials like PVDF and PTFE, BDiR ensures resistance to UV, weather, and thermal expansion.

Pre-Tensioning: The fabric is stretched to the correct tension before installation, preventing sagging and ensuring a taut, smooth surface that resists external forces.

BDiR offers custom design, load analysis, and premium materials to deliver durable and aesthetically appealing tensile fabric structures. Our team ensures that every project is tailored to local climate conditions, with a focus on wind load, snow load, and live load stability. With experience in stadiums, exhibition halls, and large public canopies, BDiR is your trusted partner for safe, durable, and elegant tensile structures.
