Clay Tile "Boost" Weight 1

[ReverenceEng]

Hello all,

After scouring the internet for weeks, I figure I'd turn here for what will probably be an easy answer.

I'm working with a two-piece mission tile that weighs 10.7 psf, but the designer is calling out a 30% boost.

I know what "boost" is, but can't seem to find any resources that talk about the additional weight for a 10%, 20%, or 30% boost.

I would assume adding a 30% boost might add some significant weight.

Does anyone know of where I could find a table of weights including this information or at least have recommended values?

My big question is - how stringent do you need the roof weight to be? even a 50% increase in total roof weight is adding 5 PSF - if you assumed your roof weight was 16 PSF would that be a big issue? Are you thinking this could potentially double the weight? Versus the entire roof assembly, plus roof live load, is it potentially a very large affect?

Right now I am adding 6 psf for the boost, so I am comfortable with that for the 30% boost in this specific situation, but I was hoping to find some more general information on the matter.

Ah well...looks like we'll chalk this one up to "engineering judgement" for now...

Boosting can be done with mortar or with tile strips. Tile strips weigh less. Mortar can get heavy, but not inordinately so. Your 6psf increase is reasonable.

Personally I think it is one more dumb idea by an architect.
