Masonry coefficient of friction
Masonry coefficient of friction
(OP)
I am reveiwing the lateral force demand on an existing unreinforced masonry brick wall. I am looking for the allowable shear stress for a masonry brick wall and the coefficient of friction of masonry on masonry?

I would also be careful in claiming it.

BTW, seems to me that the foregoing applies to new construction and not existing URM..which brings me to code provisions for dealing with existing URM.
LA City had developed a program which became codified and designated as Division 88 (Earthquake Hazard Reduction in Existing Buildings)in the LA Building Code. Div 88 had provisions for URM buildings and many other jurisdictions in CA later adopted similar regulations. It is my understanding that Div 88 has been
For URM walls utilized to carry vertical and sesimic loads, under Division 88, in-place shear tests or core tests were required to ascertain the shear strength. These results were then taken into account in the lateral analysis.
Have you considered testing to determine shear?
