Tensile Membrane

Everything You Need to Know About Tensile Structures

A tensile structure is made up of exclusively tension-carrying parts with neither compression nor bending. Tensile is not to be confused with tensegrity, a structural form that includes both tension and compression aspects. The most frequent sort of thin-shell construction is a tensile structure. Compression or bending elements, such as masts and concrete structures, are used as roofs since they can span great distances inexpensively and efficiently. Tensile membrane structures can also be employed as whole buildings, with sports facilities, warehousing and storage facilities, and exhibition halls being some common examples.

Classification of Tensile Membranes

Membrane-tensioned structures, mesh-tensioned structures, and pneumatic structures are the three primary classifications in the subject of tensile construction systems. The first concerns constructions in which a membrane is kept in place by cables, allowing tensile stresses to be distributed through the membrane’s form.A protective membrane is supported by air pressure in the third case. The second type of structure is one in which the intrinsic forces are carried via a network of cables and transmitted to different parts, such as sheets of glass or wood. 

Tensile Membrane Materials

There are a variety of natural and synthetic fibers available today that could be utilized to make membranes. However,structural textile membranes, as well as the need for a series of detailed experiments with the material and its joints, have resulted in a limited selection of fibers for general usage. Tensile membranes are usually made of coated or proven textiles. Nonwovens of various sorts are used in a variety of applications. 

PVC-coated polyester: 

UV stabilizers, fire-retardant chemicals, and anti-fungicides are all included in the PVC coating that is sprayed on polyester. Polyester fabrics with a PVC coating have a structural lifespan of more than 20 years. For both permanent and temporary tensile fabric structures, PVC-coated polyester might be a good choice. When compared to PTFE-coated glass cloth and ETFE, PVC-coated polyester is noted for its superior strength, flexibility, translucency, and affordability. 

PTFE-coated glasscloth: 

The material’s original life expectancy was 25 years; however, this has already been exceeded, with current projections ranging between 30 and 50 years. DuPont invented PTFE-coated glass cloth in the 1960s, and it has been used to make tensile fabric structures since the early 1970s.


If thermal insulation is a top priority for your project, ETFE is a great option. While ETFE is a film rather than a fabric, it is worth mentioning because it is frequently employed as a structural glass replacement and is quickly expanding in its uses. 

UV protection and improved wind resistance, in addition to being more weather-proof and lighter in weight than sticks and animal skins. They’re also protected against UV rays with UV-resistant coatings.Tension membrane structure installation is generally faster and more cost-effective than standard construction projects when correct construction procedures are in place by design-build specialty contractors for tensile architecture. Tensile fabric building constructions provide an abundance of daytime light underneath due to the transparency associated with nearly all fabric alternatives, making it an inviting and comfortable space below. Membrane structures allow architects, designers, and engineers to experiment with form and build aesthetically fascinating and iconic structures due to the fabric membrane‘s unique flexible qualities. When it comes to covering huge sections of space, the membrane’s lightweight nature makes it a cost-effective alternative for long-span applications while also providing column-free space. As a result, when compared to typical building goods, tensile membrane requires fewer structural steel supports, lowering project costs for building owners. As a result, tensile structures have a substantially lower weight and overall cost than traditional roofing systems. With the use of stainless steel, additional usable space free of columns becomes accessible. Due to the structure’s small weight, it will not be subjected to significant acceleration forces during seismic activity.

Frequently Asked Questions

A biogas dome structure is a type of anaerobic digester used to convert organic waste into biogas through a natural biological process. It typically consists of a dome-shaped container where organic materials are broken down by anaerobic bacteria to produce methane-rich biogas.

The biogas dome operates through anaerobic digestion, where microorganisms break down organic matter in the absence of oxygen. As organic waste decomposes, methane and carbon dioxide gases are released, which are captured and collected as biogas.

Biogas domes offer numerous benefits, including renewable energy generation, waste management, reduction of greenhouse gas emissions, production of nutrient-rich organic fertilizer, and potential cost savings on energy bills.

Biogas production from organic waste helps mitigate climate change by reducing methane emissions from decomposing waste and displacing fossil fuel use. Additionally, it helps in waste diversion from landfills, reducing leachate and methane emissions.

Regular maintenance of a biogas dome includes monitoring gas production, temperature, pH levels, and agitation of the digester contents. Routine tasks may include cleaning, repairs, and ensuring proper mixing of feedstock.
