his paper presents the study and analysis of URM-Buildings (Unreinforced
Masonry Buildings), traditionally used in Albania. This typology was built
in the 1980s to 1990s. Also these structures are designed with the Albanian
design codes KTP-78. Building type 77/5 is selected to be analysed, since it is
considered as the most problematic model from the building stock designed
before the 1990s, based on its plan geometry. The focus will be on the Modal
and the Static Non-linear Analysis Pushover of this 5-Storey building, based on
Albanian spectral demand and capacity curves. In this work the peculiarities
of the global response of URM-buildings are shown with the aid of a simplified
non-linear element model, realized with AM Quake v6.0 software, able to
reproduce earthquake damage to masonry buildings and failure modes
observed in experimental tests. Among the different methods developed in
the last years, this work will follow the inelastic (constant ductility) response
spectrum method. The application of this method to Albanian URM-building
typologies points out the difficulties related to existing masonry buildings;
the methodology, developed for concrete structures, shows some problems
when applied to URM structures in relation to the own characteristics of this
structural system. Traditional masonry buildings have often very flexible
diaphragms (in some cases made of wood) and this prevents from assumption
of absolutely rigid floors. Furthermore, a different architectural disposition of
walls may contribute to localize damage to ‘unexpected’ parts of building, due
to irregularities in plan and elevation.
