It is important to provide forms that are durable against wind power, rain flow, snow accumulation and other load conditions it may face, through pre-stressing by paraboloid (saddle curve form) by taking into consideration the stressing characteristics of textile materials in membrane shell structure design for making designs suitable for the project owner's functionality, aesthetic and economic expectations, for making the load distribution correctly and for the most optimum engineering solutions.
A "Static Analysis" is conducted on the specified equilibrium form by considering the structure's status of not being geometrically linear based on current specifications. There are computer programs that use the "Force Density" method in calculations, and analyze based on the status of not being geometrically linear. The limitations and regional load combinations set by international standards and specifications are always taken into consideration while making the analyses.
The following works are carried out in order during the project design stage, and the final manufacturing projects are created: determination of the membrane form via pre-stressing loads, design of the membrane "patterns" according to compensation calculations, execution of static calculations according to snow, wind and earthquake loads, making the membrane and steel manufacturing projects and shop drawings, determination of the static loads to affect the current supporting steel construction.
For membrane fabric, the form determined as a result of the static analysis is cut as strips to prepare cutting patterns (patterning process), and welded by a suitable method.
CLICK for basic membrane forms.
The design and principle details of the membrane structure are prepared by the guidance of the project owner and in line with the principles of aesthetics, functionality, safety, economy.
After its form and clearances are determined according to the owner's request and functionality, the design is later visualized as a 3 model. A "Static Analysis" is carried out on the selected equilibrium form by considering the structure's status of not being geometrically linear based on current specifications.

» Execution of static calculations according to taking snow, wind and earthquake loads.
» Determination of the static loads to affect the current supporting steel construction.
» Design of the membrane "patterns" according to compensation calculations.

The form determined as a result of the static analysis is cut as strips to prepare cutting patterns (patterning process), and welded by a suitable method.
» Panels are determined
» Panels are chosen
» Cutting lines are determined
» The cutting patterns are made smaller by considering the tensioning losses to occur due to expansion of the material in time by the tension applied, and due to its extension and shrinking under loads. This way, the surface is constantly subject to tensioning.
