I live in Oregon where sooner or later we’re likely to see a big, BIG earthquake. I wonder if this forum has any wisdom on how to plan ahead to make a storve that can survive it. Ellie
Lower wider design, such as a cookstove with a bench will help reduce amplification of racking forces…
Some codes (eg california) require running metal rods from foundation to cap. But this can be both challenging and problematic.
My preference is to skin the outer face of heaters with a high-fibre cob, which acts as a cohesive mesh.
Also,
I like to bring redirod studs about 6" out from under the metal in the slab. I also tie 4.5oz fibremesh into the slab pour so that I have a bout 1’ worth of it heading up the wall in a cementitious sandwich - ala eifs layups. If concrete block wall I use a recipe of:
1 part thinset
2 parts portland
3-4 parts masonry sand screened thru 1/16th bug screen.
If plastering up clay brick wall I use 1 part clay 2 parts fine sand base mortar to parge the mesh in.
Then either which way go over it with at lease 1/4" of following mix
1 part finely chopped straw
then 1.5 part part gooey clay on top of that
then 1/2 to 1 part fine sand.
then I place a handful of lefft over soft rockwool on top of the slurry
and start mixing by pressing the big egg beater bit straight don thru the roxul.
this disperses it evenly. Seequence of adding ingredients is important cuz lighter stuff wants to float and heavest stuff wants to sink… saving you some time…
This is a beautiful mix once you get the viscosity right. makes for a highly fibrous (= holds shit together) but also easy to spread
