Methods used for the structural evaluation of masonry structures and monuments are presented in this article. Limit analysis is initially presented as a tool for the study of the collapse mechanism and limit load of masonry structures. Unilateral contact-friction laws are introduced between the stones, to describe damage due to opening-sliding. Related applications to masonry arch bridges as well as comparison with experimental investigations, are presented. Νon-linear finite element analysis, using similar concepts taken from non-smooth mechanics, is also presented. Eventually, numerical homogenization methods are adopted for the evaluation of masonry walls. A microscopic sample (Representative Volume Element) consisting of masonry and mortar joints is chosen and average stress and stiffness are derived numerically. Then, they are used within a macroscopic homogeneous model, for the representation of the structural response. Applications of the mentioned approaches to masonry bridges and walls offer a further insight on the response of these structures.
