Abstract:
Past and recent earthquakes have highlighted the seismic vulnerability of masonry buildings by promoting, over the centuries, the development of alternative solutions such as with reinforcement in order to improve its ductile characteristics and force distribution. One of these ideas is to merge with each other structural elements on the wall, in this case leading to "dual systems". For example, the systems "Gaiola Pombaline" or "baraccata Casa" (originally developed in Portugal and Italy), are based on the idea of reinforced structures through walls of wood - framed, then, since the beginning of the twentieth century, by author, Ph.D., S.Cattari and S. Lagomarsino and the usage rise of reinforced concrete (RC) has led to the adoption of solutions of mixed masonry buildings with reinforced concrete. The aim of this diploma is the study of structural system used in Albania, especially the comperisson in between dual system and frame system, distribution of seismic forces in shear walls as well as the effect of shear walls on the structure.
