Tensile Membrane Canopies for Corridors and Walkways – Breathing Arteries of Campus Life

September 02,2025

On many campuses, there are often open gaps between classrooms, dormitories, dining halls, and libraries. It’s very inconvenient for students and teachers when they are moving between the buildings and exposed to bad weather. The covered walkways are a common solution; however, people will feel dark if without any light system, and concrete material makes people feel a sense of coldness and rigidity.

A light and open tensile membrane covered walkway could be a refreshing option, which links main buildings on the campus in a more natural way. The semi-open design of tensile membrane canopy keeps out rain and strong sunlight, yet still allows people to feel the breeze and light around them. On rainy or snowy days there’s no need for umbrellas, and in summer the tensile fabric canopy offers welcome shade, so that it’s much easier and more comfortable for crossing campus.

It’s a pleasant surprise that the bright and open corridors not only as walkways but also as channels for communication and connection. The tensile fabric canopy’s bright, airy spaces invite chance encounters, quick chats, or even small discussions, helping to create a livelier sense of community. The open design of tensile membrane roof encourages air flow, keeping the walkways cool, fresh, and pleasant to use.

Innovative Roof Designs for Stadium

January 13,2025

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.

Efficient, Aesthetic, Sustainable, and Cost-Effective: The Future of Membrane Facades

December 27,2024

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.

Tensile Fabric Structure Installation: Considerations for Installing Tensile Membrane

December 13,2024

Membrane structures, especially those made with PVDF membrane materials and tensile membranes, have become a popular choice in modern architecture due to their unique aesthetic appeal and outstanding performance. However, like any complex construction process, the installation of membrane structures requires careful attention to detail to avoid common mistakes that can affect their appearance and longevity. In this article, we will explore the key points to consider during membrane structure installation, highlight typical installation errors, and provide guidance on how to ensure a smooth and successful installation.

One of the most frequent issues encountered during membrane structure installation is membrane scratching. This typically occurs due to mishandling or improper use of tools. Scratches not only detract from the appearance of the membrane structure but can also reduce the durability of the material and potentially compromise its structural integrity. It's crucial that workers handle the material carefully and avoid contact with sharp objects or excessive force that could damage the surface.

A key feature of membrane structures is that the membrane must be tensioned correctly to maintain its shape and functionality. If the tension is too low, the membrane may become wrinkled or sag, which can negatively affect the aesthetic and stability of the entire structure. Proper membrane tensioning is vital to ensure the structure looks sleek and performs as intended.

The stability of the support frame is crucial for the overall integrity of the membrane structure. If the frame’s joints are loose or there are any signs of instability, the tension applied to the membrane may be uneven, resulting in deformities or, in severe cases, structural failure. Ensuring that the support frame is securely anchored and stable before beginning the installation process is essential.

Before starting the installation, thoroughly inspect both the membrane material and the support frame. Check the membrane for any scratches or damage, and ensure that the PVDF membrane is smooth and undamaged. It’s also important to verify that the support frame components are secure and all joints are properly connected.

Having the right tools is crucial for a successful installation. Make sure the tensioning equipment and other necessary tools are ready for use. The tensioning equipment should be capable of applying the correct force to achieve the desired level of membrane tension, ensuring that the material is taut and properly aligned.

The first step in the installation process is to gently unfold the membrane. This must be done carefully to avoid any rips or contamination. It's important to spread the membrane on a clean, flat surface to avoid dirt or debris from sticking to the material.

Once the membrane is unfolded, secure the edges using clamps or other fixing devices. This step ensures that the membrane remains in place without being overly stretched or too loose. The membrane should be slightly taut, but not yet fully tensioned.

he final step is to apply tension using the tensioning equipment. This must be done gradually to ensure that the membrane is evenly stretched across the frame. Take care to avoid over-tightening, especially in certain areas, as this can lead to wrinkles or sagging. Adjust the tension gradually, checking that the entire surface is uniformly taut.

Installing membrane structures successfully comes down to three key steps: "Inspect, Fix, Tension." Paying attention to detail in each of these stages is crucial to achieving a high-quality installation. Inspecting the materials for damage, ensuring the support frame is secure, and carefully tensioning the membrane are all fundamental to the long-term success of the project. With proper planning and attention to detail, you can ensure that your membrane structure is not only aesthetically pleasing but also durable and functional.

What is a Tensile Fabric Structure? Why Load Analysis is Essential

December 07,2024

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.
