Factor of Safety for Overhead Water Tank
Factor of Safety for Overhead Water Tank
(OP)
I have been tasked with installing a 500Gal water tank about 8 feet in the air. The thing is that the only place we have to install it is right above a common walk way. I am in the process of designing the framework to support this, but where I am not sure is what factor of safety I should strive for with this framework. I was thinking that a minimum of 5 would be good since people will often be around/under this tank. Any recommendations are appreciated.
Thanks,
Thanks,

But since it is only (1) tank, using such factor of safety won't be a problem.
good luck

It is actually wind that I am the most concerned about. This is quite a bit of weight at a relatively high center of gravity. I am afraid once it starts to slosh we will have a vibration situation and could then have larger issues on our hands.
Thanks for the replies.

If you have high winds in your area, the support structure will need to be designed to prevent "sloshing". If you have seismic activity in your area, your building code gives adequate design criteria to design for that.
I do not oppose using a slightly higher safety factor than usual because the cost is pretty small but a factor of 5 seems a bit conservative.
