Tensioned membrane and fabric tensioned structures are well-known for their unique flexible features. Engineers, designers, and architects experiment with the forms to create iconic, visually appealing structures. The tensile structure’s membrane weight is less. It requires minimal structural steel to hold the membrane in place without causing safety issues. Compared to traditional roofing systems, they invite less overall cost. 

Avail more free space!

These structures use quality stainless steel. It doesn’t create columns, thus freeing up precious space. Since the structure weight is minimal, it doesn’t experience acceleration force, especially under seismic actions. They are available in diverse shapes and types. Each one is known for its unique application and specialty. Know them in detail to make the correct selection. 

Know the different types!

The three primary classifications are pneumatic structures, mesh tensioned, and membrane tensioned structures. The latter refers to those where cables hold the membrane. It allows easy distribution of tensile stresses throughout its form. Mesh-tensioned structures refer to those where cable mesh carries intrinsic forces. They transmit this force to separate elements, like sheets of wood or glass. Pneumatic structures have a protective membrane supports through air pressure. 

Understand the types in detail

1. 3D tensile membrane structures

Such structures combine tensioned elements. Their compression is transferred to the central mast from which it is transferred into the ground. It manipulates the framework with diverse geometric shapes. The tensioning membranes convert simple facades and lines by creating pitches and beautiful arches. They can convert ordinary buildings into extraordinary-looking, iconic structures. Some examples are tensegrity structures, 3D cable trusses, and bicycle wheels. 

2. Linear tensile structures

In this structure type, cables hold the membrane. It allows tensile stress distribution throughout its form. All members in these structures are linear tensile forces. Compression members support these linear members. However, tensile members perform primary loads. Some examples are straight tensioned cables, draped cables, cable trusses, suspension bridges, and cable-stayed trusses or beams. 

3. Diverse tensile membrane structural shapes

Tensile fabric structures are a favorite of developers and homeowners compared to conventional building products. They form excellent choices for entertainment venues like amphitheaters. It provides walkway coverage at transit rail stations for travelers. Tensile fabric structure suits athletic fields, thus promoting year-round competition. Know more about them in detail to make an appropriate selection. 

4. Surface-stressed structures

They are similar to other tensile structures. However, they have tension-bearing members as surface members. They are used to build dome tents and facades. Air pressure supports the protective membrane. The types offered are prestressed membranes, gridshells, fabric structures, and pneumatically stressed membranes. Contact the reputed tensile structure manufacturer to know more. They can provide guidance. 

5. Synclastic or anticlastic structure: They are structures in which curvature centers are located on the surfaces’ opposite sides. They are referred to as saddle shapes. An example of an anticlastic surface is a hyperbolic paraboloid. On the other hand, Synclastic structures refer to those where curvature or centers are located on the same side. The latter is dome-shaped. Air pressure created within the dome inflates, develops, and maintains the tensioned surface form. 

6. Canopy or Conical Tension structure

Conical designs might feature multiple or single masts. Membranes are tensioned in both the options between the lower supporting column perimeter and the ring present at its pinnacle. Cones help cover large areas. They protect from snow and heavy rain. Masts might serve as flying masts or be installed on the ground. The tension supports the mast in the air, allowing more space below. PVC or PTFE is tensioned between the ring at the lower support column perimeter and the pinnacle. Cones are beneficial in places requiring adhering to high snow or rain load regulations. 

7. Cable net structure

They are basic components of lightweight membrane structures. They are blended with sophisticated lightweight PVC, PTFE, and ETFE membranes. These structures require minimal support which allows designing stunning structures. Durable tensile roofing applications use these structures, especially in large spaces or stadiums. For lightweight architecture, cable grids or 3D cable nets are excellent options. 

8. Barrel Vault or Parallel Arch structure

This curved structural type carries heavy loads around the opening. They transfer the load around the arch profile to piers, jambs, or abutments on either side. Structurally, arches are stable in compression. The reason is that loads are balanced evenly throughout their form. Barrel types may be affordable depending on their spans. It is because of their repetitive design nature and material efficiency. 

Tips to select the most appropriate tensile structural material

First, identify the type and shape of the tensile structure to select. The next task is to choose a worthy material that fits your needs. Your material choice depends on the investment, design, life, fire prevention requirements, and functionality aspects of the building. Talk to the industry experts and specify your exact requirements. Pay attention to diverse factors. 

Primary points to consider

The first point is self-cleaning, anti-aging, and durability features. The membrane structure should adapt conveniently to diverse climate aspects. Tear strength and tensile strength are the next feature to consider. It should meet membrane structural construction needs and avoid waste. Hence, check the pre-stress and visual membrane structure area to select the film materials to fit specified technical parameters. 

Fire resistance features

It is another feature you cannot ignore during the membrane material selection process. The structural material should be non-flame retardant or flame retardant material. The selection depends on the building’s function and the surrounding environment. Location determines membrane structural material, grade type, and fire resistance features. Ignoring such aspects may only put people and assets at risk.

Price

It is a vital factor to consider. Material quality determines its price. Budget decides your budget. Different brands, types, and membrane structural materials differ in performance. Hence, the price structure is also different. Remember, imported film prices are higher than locally produced ones. Know what you require and your budget. Select accordingly.
