stability of steel containers under high wind conditions

[container]

I need to calculate the stability of a steel box, dimensions 2.45M cube, with a 300 KG/sq M roof load (dead load + live load) and a 200 kg/sq M floor load (dead +live) in the presence of a wind blowing at 100 km/hr. Further, what will be the stability of two such boxes, one stacked on the other ? Can anyone help in calculating ?

The first thing to do is to calculate the wind loads acting on the containers in accordance with the applicable code in your area - BS 6399 here in the UK.

You will then be able to calculate the disturbing and restoring forces and moments on the container assembly. Incidentally, the restoring forces should be based on dead loads only, as in theory the containers may be subject to wind load without any imposed roof or floor loads being in place.

You may also want to check the connections between units to ensure that they are adequate.

If the assembly is found to be unstable, you may need to provide kentledge to increase resistance to sliding or overturning.
