Hi,
I am reading the Specs for a theater that is currently being built, and one sentence caught my attention:
"Design the wire rope grid so that when wire rope assemblies are torqued to factory recommendations,
the wire rope shall not deflect more than 2 inches under a maximum concentrated
load of 300 pounds."
So my question is, how do one approach the load calculations for a wire tension grid? Do you treat it as a walking surface (say, a deck) and calculate load per square inch (ft), or do you isolate every single cable and calculate point loads for it? In the latter case, how do you approach the fact that wires are interwoven on 2" centers? The same with the deflection: do you calculate it for a single cable, or for a certain area?
By the way, I am of course not designing a wire tension grid, I am just curious about how it works.
Thanks a lot!
