Models for numerical analysis of stone structures

We have recently witnessed the destruction of many existing and valuable stone structures in ancient urban cores of European cities due to warlike situations or earthquakes. Assuming that we are interested in safety aspect of existing structures under actual and increasing loading conditions, we have become aware of the tasks imposed by present situation, i.e. to preserve such structures which usually have some historical importance. while some small structures will be reconstructed by simple civil engineering and stone-cutting works, other more significant structures or their details will require complex analyses. This paper presents some aspects of numerical modelling of stone structures, namely three numerical models based upon finite element techniques which can be used to perform numerical analyses of stone structures. these three models are: (1) standard linear model; (2) linear model with contact (interface) elements; and (3) non-linear elasto-plastic (orthotropic) model. The application of these models will be presented on some characteristic details of stone structures.
