So if you have a beam 20ft long the allowable deflection limit is 20ftx12in ft 240 1.
Ceramic tile deflection limits.
Some large natural stone tiles that aren t as uniformly strong as ceramic tile may require an even stiffer structure.
These deflection limits apply both to the framing supporting the substrate and to the substrate itself for example when a concentrated load is applied between joists.
Ceramic tile live load deflection shall not exceed l 360 stone tile live load deflection shall not exceed l 720 the owner should communicate loading requirements to the designer designer and contractor must make allowances for all live and concentrated loads including during construction and maintenance such as heavy.
The subfloor areas over which stone tile is to be applied must be designed to have a deflection not exceeding l 720 of the span.

Whether you are installing stone or ceramic tile over floors and walls there s one thing to consider.
Mia suggest in their standards to use a stricter total load deflection limit of l 720 where stone tiles are used.

Until recently the tile council had specified a standard for ceramic tile only based on using test equipment that was intended to limit deflection of floor sheathing.
And since it is small i will leave the source for where it is found here 1.
The tile council of america recommends that deflection be limited to l 360 l span length in inches under total load for ceramic tile.
