Localized stress percolation through dry masonry walls. Part II – Modelling

Abstract

The highly localized stress distribution found within dry masonry walls through transmission photoelasticity in Part I of this article is explained both proposing a micromechanical model (based on a form of random cascade transmission of forces between bricks, which includes random coalescence additionally to random branching) and applying a phenomenological description (based on the extreme orthotropy of the equivalent homogeneous material).
