Too Much Weight?

[clipperfish]

Jaws . One of my Clients is a structional engineer. He tells me that all condo and apartment (that are made of wood even with 2 inches of concrete for sound proofing) .rate at 40lbs constant. And all concrete buildings are 50 lbs constant. He told me that the way my stand is built it should not be put on the second the second floor ,Because i have only six 2x4 for legs , he said if i was to put in more 2x4 I can move up to the second floor because that would lower the amount of weight that is being put down on the floor per sq. ft. Hope this helps some .

Your floor can hold a lot of weight...as long as it is spread out. You will not have a problem with 3000lbs spread over 12 square feet. I had the same question and a friend of mine talked to some engineers at his worksite and they pretty much laughed at the concept of 1500lbs going through the floor when it is spread out over 8 square feet.
I'll get a hold of the guy again and send you the standard joyce weight limits....its pretty high per square foot.

I just had to go through the same question as i am making my new tank which is 96" long. The floor is over the garage and its in cement. A civil engineer came to my place, look at the plans and made all the calculator to see if the floor can support the floor. I had previously a 180G tank and now going for 420 + sump for around 600G. After calculation, he told me that my 180G was already overweight, even if it was holding, with time, it might have been dangerous. For my next tank, there will be a jack post in the garage to support the weight, actually 2 to make sure.

That'd be great. I'd be interested to hear his opinion too. Thanks guys.

I think I recall my Dad (Engineer) mentioning a possible 300lb load per square foot spread out like a tank would do should be fine? I wouldnt be surprised if your condo could handle double your current loading. If the 180 was OK'd by the contractor, I wouldnt even worry about the new stand since it will be in the corner.

Ok, sorry it took so long to get back to you but I am having computer difficulties at home (hope nobody at work notices that I what I am doing). A joyce is supposed to be able to support over 1000lbs per square foot. Now that is before you start adding everything (like concreate floor) onto it. Also, my friend was told that the length of the joyce and support will also determine how much weight you can have over the entire length of the joyce. Anyway, with the description of the dimensions of your tank, and the fact that it is against a load bearing wall you should be fine.

Thanks guys. I don't sleep much now anyways because I've got over 200G and over 3000lbs of water on the third floor. What's another lost hour?
