Abstract

Part of this paper refers to a research study developed by Jossa and the writer [1] now awaiting publication. It is well known that the static and kinematic behaviour of ancient dry block masonry structures is predominantly regulated by two parameters: self-weight and friction. And it is also well known that any investigation on the safety levels of these structures implies difficulties of analysis, due to the non-associated flow rules imposed by friction. Possibilities of non-unique solutions are directly consequent. This is, therefore, one of the main problems in every programme for the conservation and repair of such structures. The basic guideline of this research is to provide appropriate requirements to treat frictional materials within the framework of the standard limit analysis. This is pos
