| Abstract: |
Tensioned textile membrane structures are now common in the field of construction and they are the subject of a standardization process to harmonize the design rules among Europe. The stiffness of the structure relies on the pretension of the membrane, which can be provided mechanically or pneumatically. The stiffness of pneumatic structures depends on the internal pressure. They are able to support external loads which are much more important than their own weight. A first reliability study is conducted on a two parallel inflatable beams structure, which can be used as a footbridge. The serviceability limit states (SLS) and ultimate limit state (ULS) are defined. The reliability analysis is conducted with the FORM method, providing reliability indices as well as sensitivity factors. |
