Tent Design 1

[dik]

Can anyone recommend a relatively simple text on Tent Design? The tent is straight forward with no odd features. Ridge with pole support, eaves with pole support, and 'tension ties' anchoring it to the ground. I assume maximum loading is wind, maybe some rain... no snow, and maximum loading determines fabric required strength, max tension tie loading for rope? capacity Anything else that I should be looking at... did a bunch of stuff with Frei Otto's work about 50 years back on membrane/cable structures.

Circus size?

40'x60' with a 22' ridge, open sides, like a hip style roof. 2 centre supports and perimeter supports at 10' o/c. Reinforced polyester... support loads given and anchor forces given... also design wind velocities and gust duration. just a matter of quickly checking. Design to ASCE-02, IBC-06, and IFC-06(?). Any significant changes to ASCE that might be interesting. For a short term loading and I can correct wind loadings for different return periods.

Sorry I have nothing, but at least we know what you're talking about now.

dik,

Something from MIT may help, at least, to get some insight on "tension fibric structures". Link

Here is another read to help on wind design. Note that it mentions another document, ASCE 55-10 "Tensile Membrane Structures", which was adopted and referenced in the IBC code (per the author). Link

looks good... will read it tonight... thanks, and thanks for the ASCE link... we'll see what ASCE 55 is all about.

I think experienced people on this type structure are scarce, good luck.

Thanks... never too old to find something interesting or have it land on my doorstep... this is the engineering stuff I live for... Catch Wiki

https://en.wikipedia.org/wiki/Frei_Otto.

He was the 'go to' guy 50 years ago when I first started. One of my first projects after graduation was a cable supported structure. I seem to recall that US Steel had a couple of books out on cable structures back then... my copies likely ended up in Mexico. One summer there was a Mexican student up at the U of M and he was complaining about the lack of good texts (they had excellent concrete texts at the time). One of my classmates and myself packed up all our books in a crate and shipped them down.

Wow, From the wiki:

"Otto died on 9 March 2015; he was to be publicly announced as the winner of the 2015 Pritzker Prize on 23 March but his death meant the committee announced his award on 10 March.[4][5] Otto himself had been told earlier that he had won the prize by the executive director of the Pritzker Prize, Martha Thorne. He was reported to have said, "I’ve
never done anything to gain this prize. Prize winning is not the goal of my life. I try to help poor people, but what shall I say here — I'm very happy."[5]"

HIs work was fabulous, and advanced. A good engineer in spite of being an architect.
