The tensile force in light membrane structures is a key characteristic for their operation, not for nothing are they also known as tensile structures.
Membrane structures or light membrane structures are usually admired for that aesthetic touch that a construction or space gives them, however they also cause curiosity because their manufacture and assembly is different from traditional works in architecture.
It is for this reason that many may find it strange to say that a membrane lightweight structures was “built”. The reality is that a membrane lightweight structures is installed, erected. A membrane lightweight structures is rather manufactured, assembled and then tensioned.
And it is that although in textile architecture construction materials are used, such as steel, which its quality in manufacturing is mainly controlled in the workshop, there are more factors at play to achieve the lifting of a tensile structure, among them, the tensile force , also called or known as pre-effort, stands out as one of the most important if not the main one.
The initial pre-stress or tension gives the tensile structure or ensures the rigidity it requires to withstand possible loads or forces due to self-weight, rain, hail and wind, among others. Without this initial tension (with the value that results from the structural analysis), the membrane, being a textile, could not function as a structural element of the system.
Some textile architecture firms send their external tensile structures to be calculated, since they do not have an engineering department or area. And it is that a vital part for the installation of a membrane lightweight structures lies in calculating the tension force that it must carry.
At Hyparch we have our own engineering department to calculate the tension force of any project. We invite you to visit our online quote so you can choose the membrane lightweight structures that best suits your space.
