Yield design modelling of dry-stone retaining walls

Abstract

Over the past few years, there has been a steady increase in the interest in dry-stone walling not only to preserve existing constructions but also to build new ones. Yet, no structural design method has been validated till today. In this study, a simplified model dedicated to dry-stone is propounded. This simulation, implemented in the rigorous framework of yield design homogenization, can meet engineering expectations. First, the model is introduced, and the parameter measurement detailed. Then, the validity of the method is assessed by comparisons with micro and macro-mechanical methods, and field trials. As a conclusion, possible improvements of the model are discussed.
