How to calculate safety factor for a tank both under and overbuilt?

[kevensquint]

Hi, let me explain. First none of the online calculators accommodate my situation. Its a 60"L x 30"w x 20" h shallow tank. The builder did not make it all with 1/2". It is 1/2" bottom, 3/8" sides. Since I was not convinced of its integrity with 3/8". I did a 3" wide top and bottom eurobracing using 1/2" as well as a 10"w -1/2" center brace. It looks very solid altogether, and the water level is set to 17.5"h. I'm hoping for a safety factor of about 4 to tell my insurance. Any help? Thanks

I am not sure where you can get an accurate calculation online. The tank builder should provide the safety factor if it is requested.

He already built it wrong, not sure he's my guy for calculating.

*I've seen some very aquarium build savvy responses online, I figured this a decent place to ask if an engineer type person catches my post.

Half inch, all panels. even with a euro.

Do you have a reference? Off the top of my head wanted to be 100% safe I agree. However I am stuck with this tank and according to online calculators 3/8" at 18" h is ok. Therefore there must be away to factor in extra bracing etc.

60 x 18 with a euro is .50. half inch acrylic is actually smaller than .50". the calculator is slightly off and not exact.
