- •
Stone masonry walls modelled using random field finite element micro-modelling.
- •
Grout injection studied using randomized material properties for the stone and grout.
- •
Contact properties had the most significant impact on the lateral displacements.
- •
Overall, the addition of grout predicted collapse prevention of the wall sections.
