Canvas Roof

Although tent shelters are a system based on ancient times, it has been started to be used in ambitious and large openings such as stadiums, sports halls, market places, roofs, sunshades and so on, with the advancement in technology.

The design of these systems will become more widespread with the understanding of the working principles of the systems. Tension structures, unlike traditional construction systems such as reinforced concrete, masonry, steel and wood, whose bearing is provided by their bending stiffness and weight, are completely or partially using membrane covers and/or ropes with negligible weight, flexible, only tensile strength. building systems. For this reason, the structural design and application of tensioning systems are different from other construction systems.

Project Design and Pricing Process

In traditional building systems, the form is known in advance. The aim is to determine a carrier system suitable for the form and function given according to the customer’s requests and to design the structural analysis and details. The above observations explain that; The ability of tensile structures designed using flexible membrane covers and/or ropes, in other words only structural elements with tensile strength, to stand depends on the form of the surface and the stresses that occur on the surface. The surface must be in a form where the prestressing loads are balanced. This form is called the « equilibrium form ». The structural design of tensile structures begins with finding this form and determining the prestress at the surface. Also, as a new stress distribution will occur under each loading, the equilibrium form will change.

As a result, the geometry of the form of the tensile structures changes with each loading, and they remain standing in that shape. For this reason, geometric nonlinear analysis methods should be used in the analysis of these structures.

In order to obtain a balance form from any cover, it is necessary to pull the cover from at least 4 points. At least one of these points must be outside the plane through which the other three pass.

Considering the engineering and design criteria, Erdağ Metal undertakes to its customers suitable and long-lasting tensioning tarpaulin systems.
