This is my first posting to this Forum.
I'm currently designing an all glass aquarium, and would appreciate any input from the resident experts.
The aquarium will measure 1.80m (length) x 0.72m (width) x 0.65m (water height). I have just completed the construction of a reinforced concrete stand, and a load test has shown a mid span deflection of 0.8mm with a load of 940kg.
I will be building the tank from 12mm thick normal float glass.
Is there a formula to calculate the maximum deflection (before failure) of a given length and thickness glass? I'm concerned if the bottom glass can accommodate the deflection of the supporting slab, and would also like confirmation that, if the glass will deflect to this degree (0.8mm), can it still be considered to be supported by the bottom slab (or should I treat it like an unsupported slab, spanning the 1.8m between it's ends.
Thank you for any replies.
