What it is Filled
A structure whose elements carry only tension, with no compression or bending in those elements, such as membrane roofs, cable nets and cable-stayed or suspension systems; tensioned membranes and cables are anchored to masts, arches or edge beams that take the compression.
Why it exists Filled
Let an agent describe tensile structures by form, materials and design standards, and point to engineering guidance, without giving structural approvals.
Distinguishing features Filled
- Mechanically prestressed membranes commonly use anticlastic (saddle) curvature; pneumatic membranes use synclastic curvature stabilised by pressure.
- Compression is carried by separate masts, arches or rings; form-finding links geometry, prestress and supports.
- Prestress gives stiffness, but wrinkling, slackening and stability must be checked under each load combination.
What robots and AI may and may not do Filled
Must not
- approve designs or declare structures safe
Only with a human decision
- design and inspection by qualified engineers
May
- describe structures and point to standards
Moral aspects Filled
- public safety
Who is affected
- users of buildings
Owners Filled
