Soild Double Layer Brick Wall Design Guide

Hi All,

I have an existing load-bearing 8" thick double-layer solid brick wall similar to the one circled in the image below. I want to put a new beam supported on top of the wall with an end reaction of roughly 180kN. I want to check the axial ( & bending due to eccentricity) capacity of the existing brick but cannot find a good reference to carry out the calculations.

Does anyone on the forum has any experience with this or share any good reference?

Thanks!
