	Hi All, After receiving the adaptive map from a previous post , my efforts to find a local engineer to run calculations on the wind speed tip over point of a conex shipping container have not worked . Can anyone help with this. Info ,40ft hi cube 8ft wide x 9.5 tall x 40ft long. — — 20ft standard. 8ft wide. 8.5 tall 20ft long. Specs below. Would like calculations for empty weight,— -2000lbs— -and 4000lbs weight load, on floor , and for increased stability by nesting side by side. Containers are placed on flat prairie ground . previously we had these at 9000ft rocky mountain location with winds 120–130 mph. Never had any issues. Thank You http://containersolutions.net/specifications/ http://adaptivemap.ma.psu.edu/websites/friction/slipping_vs_tipping/slippingvstipping.html

F = A x P x Cd
F = Force
A = Area
P = Wind Pressure
Cd = Coefficient of Drag (for a flat surface such as a container it would be 0.6)

...as you increase altitude you decrease air density, so 120 mph wind at sea level does not equal 120 mph wind at 9000 ft altitude in force....

Specs

Typical ISO (International Standards Organization) shipping containers are manufactured with identical size specification in terms of exterior height, exterior width, and exterior length. The standardization of containers and the adoption of the ISO specification is to insure that all equipment handlers, chassis, rail cars, and slot spaces on vessels will accommodate ALL containers. This makes our job much easier, because we can confidently give you exact exterior specifications. Interior specifications can be slightly different, less then 1″ variation. These ISO containers are now available in all major metropolitan areas throughout the nation. Shipping containers as storage units have changed the storage industry, most people prefer the convenience of mobile storage vs. standard mini storage. Container Solutions has formed a network of small businesses that are familiar with your needs. This guide is designed to help you become informed about container uses, common questions and problems.

Typical Dimensions
	Exterior			Interior			Door Opening

	Solar Eagle, Would your chart/ info refer to structural failure or tipping over?

	I think that's the approximate sliding or tipping force.... ..." Q- I read that an ISBU Home is Hurricane proof. Is that true? A- Yes, ISBU Homes, either single units or multiple units connected, can withstand 100 MPH winds on a foundation, or 175 MPH winds when easily anchored with pylons. ...extremely solid in Tornadoes or Hurricanes. This has been proven time after time in many ‘real life’ situations."... http://www.isbu-association.org/faq.htm http://www.isbu-association.org/all-about-shipping-containers.htm https://containerauction.com/read-news/shipping-container-parts-and-assembly https://containerauction.com/read-news/storage-container-foundation-ideas __________________ All living things seek to control their own destiny....this is the purpose of life

	Is this the first time the forum has needed to consider the flight-worthiness of ISO shipping containers? __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856

	If you are thinking about using this for tornado protection then look at this. This may also be why engineers are hesitant to give you a wind speed tipping point analysis. __________________ "Don't disturb my circles." translation of Archimedes last words
