Abstract
In this paper we present recent developments in the field of limit analysis of masonry structures. In [1–3] we presented new a limit analysis approach for masonry vaults. The approach is based on the exact geometrical representation of the surface of the vaults and on the research of the best collapse mechanisms by means of genetic algorithms in the framework of the upper bound theorem of limit analyses. Either J. Heyman assumptions or more complex material models of the masonry based on homogenization techniques are considered and solutions are provided in a very fast and simple way. In [4, 5] the approach is extended to masonry walls in-plane and out of plane loaded and to the analysis of masonry churches. The application to the study of aggregate buildings is under development.
