STONE / MARBLE ANCORS LOAD DISTRIBUTION
STONE / MARBLE ANCORS LOAD DISTRIBUTION
(OP)
i have a project where i need to design stainless steel fixings for supporting marble / stone claddings .
i have seen many stone fixing suppliers follow the rule of considering selfweight of marble or stone to be taken only by the lower anchors ...see the attachment drawing .
but such an assumption need not be always realistic. according to me , even the upper anchors need to be equally resistant and hence the load to be shared equally by both upper and lower equally.
as i am not an expert in this field. i would like professionals to please comment on this .
also i would like to know for the expansion anchor design how they consider the allowble s for tension and shear to be taken by the expansion anchor...can we use the std. formulae from aci codes or it has be done by testing such as pullout test ..

For anchor capacity into stone, testing is best. The quarry or specialty contractor may have some values that can be used for preliminary design. The project specifications may require testing on samples of the actual stone being installed. But. I have never worked on a project with marble, maybe it has more consistent properties than other stone cladding.

You might want to take a look at the "Dimension Stone Design Manual" from the Marble Institute of America. Link The Indian Limestone Institute also has a publication "Indiana Limestone Handbook" that discusses these issues.
