Tensile Structure for Gymnasium & Football Stadium - Nanchang Sports Center

DESCRIPTION

Nanchang Sports Center has a total investment of about 1 billion Yuan. Located in Nanchang City, Jiangxi Province, China. It covers an area of about 400 acres. It consists of the main stadium (15, 000 seats), swimming pool (accommodating 1, 500 people) and youth activity center. The construction composition, the total construction area of the project is about 106, 000 square meters.

The stand of this project adopts concrete frame structure, the body is made of steel arched truss structure, and the roof is covered with Ferrari PTFE membrane. The maximum height of the structure is 50m, the length of the cantilever is up to 60 meters, and the total area is more than 22, 000 square meters. The membrane is consists of 55 Cones and 19 flats. The membrane boundary connection is a fixed platen and a U-shaped screw adjustable. We use the combination of total station and manual measurement to perform the measurement of the membrane installation control points in batches, and then cut and install the membrane.




The steel structure of this project has a large span and large force. In order to ensure the accuracy of the joint and the operability of the construction, firstly, the parameterization of the joints and sections of the components is carried out in order to improve the efficiency and improve the accuracy of the model. Secondly, the establishment of the model in the process, the precision is strictly controlled to avoid the existence of errors, and the existing problems are proposed and solved in the process of establishing the model.

The tensile structure is a good solution for large stadiums. Because the tensile structure building has many advantages such as novel shape and good light transmission, it is widely used in sports venues. The tensile structure increases the space span and easily covers the entire stand, making construction easier and shortening the construction period of the project. The unique architectural design makes the stadium full of space art.




The fabric substrate of the PTFE membrane material is glass fiber, and the diameters of the fiber should be in the range of 3.30 to 4.05 μm, and the weight should be greater than 150 g/m. The most important feature of PTFE membrane is its high strength. The medium strength PTFE membrane is only 0.8mm thick, but its tensile strength has reached the level of steel; and the lower modulus of elasticity is beneficial to the complex surface shape of the membrane. It has a wide temperature range and can be used in the temperature range of -70 °C to 230 °C. With unique optical advantages, the incident light during the day becomes natural warm light, preventing glare, no shadow, even light distribution; almost no ultraviolet light transmission, which preventing the fading of interior decoration materials and equipment; night high reflection performance makes the room excellent Lighting effects, which reducing power consumption, and can bring out the brilliance of buildings in the night sky.

SPECIFICATIONS

    • √. Large Span: Tensile Structures can create an expansive covered area, exceed to 200m.

    • √. Unique Design: Tensile fabric Structure gives architects, designers, and engineers the opportunity to experiment with form and create visually exciting and iconic structures.

    • √. Various Shape: Changeful supporting structure can make lots of different shapes of tensioned structure with flexible membrane.

DESIGN & MODEL

INSTALLATION


       Step 1: Design

       BDiR use the latest tensile structural design software to produce
       detailed tensile structural designs.


       Including:
       BIM model design (building information modeling), 
       finding and load analysis,  integrated building design,
       joint force analysis, membrane cutting analysis,
       construction process simulation, numerical wind tunnel simulation.
    Step 2: Membrane Fabrication

    Membrane fabrication plays an important role in the tensile structure.

    There are many fabrics (PVC, PVDF, PTFE, ETFE) in the market, they come from all over the world, they have different characteristics and prices, different welding or joining techniques. We will make the best choices from structural design, project location and our customer budget.


      Step 3. Steel Fabrication

      Tensile structure are made of steel structural members that are welded
      and painted in our factory.


      We will conduct the following procedures with high standards:
      Paint thickness detection, ultrasonic testing,
      magnetic particle testing,
    high-strength bolt torque testing,
      cable pre-tensioning, rust removal ,

      pre-assembly inspection, painting, etc.

    Step 4: Cable Fabrication

    Cable and hardware fittings are procured from the most reliable and certified vendors of the industry in compliance with the international quality standards.

    Cable fabrication are proceed under guidance of our skilled and experienced experts.


      Step 5: Installation

      The installation of the tension structure is critical to the overall success
      of the project.


      We will provide on site installation service. Our project manager will work
      with the client to coordinate the structure installation on site.  Including
      steel structure installation, membrane lifting and measure tension. If you
      prefer self-installation, we'll send you detailed instructions so it can be
      easily installed.


    Step 6: The Future

    Our service will not end at the time of delivery and installation!

    Because we only use the highest quality membrane materials and steel frames, cables and parts. You can rest assured that your new tensile structure is built to last. Besides, Tensile structure does not require much maintenance and we offer a up to 35 year warranty.


REVIEWS


  • Christine Deng, Director of Sports Centre

    This is a great project, and after a few months worked with BDiR, we believe that their design and craftsmanship are of a high standard. Their efforts to meet the needs of their customers are very obvious. "
