Fabric Roof Structures
Fabric Roof Structures
(OP)
I don't know why things happen in clusters, but I am getting a number of requests for the design of framing to support fabric roofs. These are typically light-weight fabric with steel cable around the edges and no structure to give the fabric any shape. I am not sure of the amount of prestressing force, if any, that is usually applied and the subsequent application of other roof loads such as wind uplift affect the horizontal force that must be supplied. Anybody have any insight?

RE: Fabric Roof Structures
Most of these structures are small and part of other projects and are architecturally driven. Can't use a pre-engineered buildings because of sometimes odd shapes, etc. So what I am looking for is a way of determining the reactions from the fabric on my structure. There are formulas out there for catenaries, but these cables are prestressed and the formulas are for essentially slack cables. Is there any difference in the behavior of a prestressed versus slack system?
