Tensile Membrane Structures v/s Conventional Structures

Tensile Membrane Structures:

The free form structures which have the ability to enclose a large space with limited supporting steel work compared to conventional roofing structures are tensile membrane structures. A tensile structure not only spans a long distance with the usage of minimum material but also gives designers, architects and engineers the ability to experiment with its shape and create appealing structures. Followings are the keys point to clarify the advantages of tensile structures over conventional structures:-

• Durability: By virtue of the protective coatings on tensile membrane structures, One can expect a lifetime of two to three decades from them. These coatings not only make the fabric structure strong, stable and tear resistant with a high degree of elasticity but also absorbs UV radiation, reflects heat away and maintain its colour.

• Recyclable Design: The tensile membrane structures are made with the fabrics which are recyclable. Hence these tensile structures feature a sustainable and recyclable design over conventional structures.

• Low construction cost & less time consuming: The tensile structures are easy to set up & the total cost of covering the large space using fabrics and steel material is very low as well. The tensile membrane structures takes even less time to set up as well when compared to other traditional structures.

• Removable: Often build with temporary solutions, the roofing membrane structures can be taken off easily and taken away to another place. This ‘Removable’ feature of membrane structure distinguishes it from conventional building

• Low Transportation cost: The Tensile structures are lightweight so whenever we need to carry its components to another place, this can be done with a very low transportation cost.

• Natural light: Created with transparent membranes, the tensile structures allows a plenty of natural light to flow in and creates an open air feeling. As these membranes can absorb the heat, the temperature under these structures also stay less.

Membrane Structures: Construction Advantages & Environmental Properties

Membrane Structure

Membrane structures were originally used to provide shelter where materials were scarce, or mobility was required. Developments in material technology and the understanding of the structural behavior tensile membrane structure mean that it is now technically feasible to enclose very large spaces with a minimum of material.

Due to variation of transmittance, reflectivity and emissivity of the membranes accomplished in the solar and infrared radiation band separately, tensile structures play a useful role in the relevance of environmentally friendly.

Besides, these structures can be used as climate modifiers in both hot and cold regions, offering in some circumstances conditions suitable for human occupation which conventional buildings may be sited and operated in a highly efficient manner.

 

Construction Advantages of Membrane Structures

The Construction of Membrane structures offer the following advantages: −

• Low consumption of resources
• Short installation time
• Limited number of personnel required
• Deployable at different undergrounds without any destructive installations

 

 

 

Environmental Properties of Membrane Structures

Roofing membrane structures have very little thermal mass & as a consequence, react very quickly to changes in the environment around them. Followings are the Environmental properties of membrane structures are:

 

1. Optical properties:

Tensile Membrane Structures (TMS) allows to control the light transmittance in the covered area. This results in the tendency of fabric membrane properties to change more significantly at higher angles of solar incidence, which greatly reduces the solar energy and heat gain that enters the structure, thus resulting in less energy used within a building.

 

2. Thermal Properties:

The large surface area of tensile structures compared to their thickness means that they have insufficient mass to significantly affect their thermal behavior. The amount and direction  of the  conduction  of heat through the fabric material depends on a number of  changeable  factors like air temperatures, the wind speed, U-value, the thickness of the fabric etc.

Tensile membrane structure

The light and freeform structure to span a long distance with the usage of minimum material (such as steel cables, columns, membrane) in their manufacturing is Membrane Structure. Besides offering many interesting possibilities ranging from railway platform roofing to sports complex, these structures are highly energy-efficient & save much money in transportation too. In the urban region, membrane structures are traditionally designed as structures with high curvature, and nowadays more and more as flat structures, in highly aesthetic way. Additionally, these roofing membrane structures begin to mixed with glass in order to produce bright filled spaces.

 

Key Reasoning Behind Their Growing Trend:

Membrane Structure

In Architectural Industry, Membrane structures have been used for more than 50 years. Besides their increasing popularity in architectural design & abundance within buildings, the main concern is to recognize the reason behind the increasing trend and growing popularity in almost every sphere of life whether it is commercial, residential or industrial. The key reasons are as follows:

 

• Aesthetic Design with fashion sense: Membrane structures can be easily manipulated into various types of shapes and are rich in color. Formation of Aesthetic night scenes with the coordination of light, gives membrane structures a competitive edge with today’s high-tech modern buildings.

 

• Less Energy Consumption: Membrane material used in the structures is relatively good in transmission of light (with 7% to 20% transmittance), not only makes full use of natural light, but also consumes least energy. This makes people feel good and dreamlike.

 

• Rapid Construction: The tailoring of membrane diaphragms, the manufacturing of steel cables, steel structures etc. are finished in factories. Only linkage, positioning & installment of steel cables & steel structures are carried out on the construction site, makes the overall manufacturing easy as well as fast.

 

• Safety & Reliability: Roofing Membrane structures are light in weight and their earthquake resistance is relatively better than other steel structures. These structures can tolerate of a huge amount of displacement in overall collapse of building.

 

• Weather Resistance: The weather resistance of membrane material is a comprehensive index, which prevents membrane structures to get affected by natural phenomena such as daylight, temperature variation, rain wash, dust erosion. This outlines its years of service, its aging resistance, self-cleaning ability and intensity attenuation.

 

• Optical Properties: The optical properties of membrane material refer to optical phenomenon like reflection, transmission, absorption and scattering. The effects of membrane material on light of various different wave bands satisfy the light requirements of various indoor activities.

 

• Fireproofing Performance: The membrane material itself is non-inflammable or flame retardant. Maintaining the stability of the framework of membrane structure in the case of fire/damage of membrane surface is one another noticeable issue connected to the fireproofing of membrane structure.
• Sufficient Durability: Stability & durability are basic mechanical properties that all building structures must satisfy. Ranging from a frigid arctic climate to hot & scorching weather, membranes such as PTFE fiberglass, ETFE film and PVC  proved to be an excellently durable and long lasting fabrics used in the manufacturing of membrane structures .
