Unreinforced masonry structures are the most widespread type of structuresaround the world. Until the beginning of the 20th century, when steel and concrete dominate the market share, masonry was the main structural material. This resulted to most of the cultural heritage buildings, being constructed with unreinforced masonry. Recent years, within the cultural heritage preservation campaign, there has been an effort to approach the static and seismic behavior of structures of unreinforced masonry. The current study presents an extensive bibliographic review of the different type of structures from unreinforced masonry, as well as methods of modelling and assessment of them. Afterwards those principles are applied to an existing traditional building, located in a village of the Municipality of Rethymnon, in order to assess its current state. Three different type of structural reinforcement are examined, so that the structure can withstood the construction of an additional floor on top of it. The examined methods are grouting, reinforcement with Textile Reinforced Mortar (TRM), as well as reinforcement of the rigid diaphragm. Finally, the reinforcement operation and its estimated cost, is described and calculated in the economic and technical study.
