hello... ı am studying about masonry structures and ı have a problem about how to obtain properties of potential brick cracks (kn and ks). ın publications there is a table about it but there is no information how to obtain it. in addition this, there are following formulations about elastic properties of joints;
kn=(Eu*Em)/[tm(Eu-Em)]
ks=(Gu*Gm)/[tm(Gu-Gm)]
are these formulation given about joints usable for potential brick cracks or is there any another?
really confused...
Check the below link out, specially explanation about Figs. 5 and 13. It talks about finding Knn, Kss and Ktt experimentally. Hope it helps.

Hi
I advice you to see this document. You will find what you need.

If a crack appears overnight in your previously intact brick house, don't panic. It is not the first
step in the total disintegration of the whole building.
Most cracks require cosmetic treatment only. The majority are not indications of grave structural damage.
Remedies can be as simple as watering the garden a bit more or less, or just waiting for the season to
change.
However it can be valuable, if only for peace of mind, to be able to recognise and evaluate the type of
cracks. You will then have some logical basis for deciding which method of correction will be appropriate.
Unfortunately lack of knowledge can lead to the adoption of unnecessarily expensive treatments which
may be suggested by firms or companies biased in favour of using their own patented and profitable
'cures'.
