The structural behaviour of Frangokastello, a mediaeval masonry castle located in Crete, Greece is studied. The structure presents several damaged areas, consisting of cracks and local failure of masonry. The finite element method (FEM) is used to investigate how the existing failure of the structure affects its mechanical response. First, an eigenvalue analysis of the structure without the cracks and a dynamic modal analysis are done. Then, a non-linear constitutive model using a smear crack law is used to investigate the limit state of the structure under static and dynamic loading. Finally, unilateral contact interfaces are introduced, to simulate the cracks which appear in the structure. This model, which consists of several non-linearities, is tested under non-linear time history analysis. Comparison of the results demonstrates how the pathology of the structure affects its response. This procedure is necessary towards taking actions for the reinforcement of the structure.
