“…In this work, the nonlinear damage behavior of the masonry is considered within a continuum mechanics theory, based on a smeared crack approach [12,13] where the cracks are not described one by one but are instead continuously spread within the body and affect (reduce) the medium stiffness, a concept that offers a variety of possibilities, ranging from fixed single to fixed multi-directional and rotating crack approaches. Here, the distinction lies in the orientation of the crack, which is either kept constant, updated in a stepwise manner or updated continuously [14].…”

“…Most of these current masonry buildings were designed considering merely gravity loads without any consideration of earthquake resistant design rules [2]. Furthermore, previous studies [3][4][5][6][7][8][9][10][11] and earthquake inspection reports have shown that masonry structures are very susceptible to seismic movements. Consequently, this typology has high seismic vulnerability over the region.…”

Recent earthquakes occurred in many parts of the world have shown that unreinforced masonry [URM] buildings constructed according to older codes may constitute an important source of risk. It is known that the mechanical response of the masonry structures depends on several factors including the compressive and shear strength of its constituents, bricks shape as well as the volumetric ratio between the wall texture and components. In this study, the effects of the material choices of a particular type of masonry buildings were studied. The typology chosen in this study represents a typified masonry building of the current Albanian building stock; these buildings were mostly built between 1977-78 and thus were designed without considering the seismic requirements proposed in today's modern codes. This template building has been constructed in different regions of the country with the same architectural and structural configuration in two versions; red clay bricks and silicate bricks. The aim of this study is to investigate the influence of these two different materials on the seismic response of the selected masonry building. The evaluation is based on the use of nonlinear static analyses, performed by using TREMURI software. In order to estimate the reliable seismic response for this typology, extensive research in terms of historical information, structural characterization and the definition of the inherent material parameters has been executed. Upon the evaluation of the obtained results, in contrast to the type of buildings constructed by clay masonry, calcium silicate one showed a stiffer and slightly stronger response. However, at similar values of in-plane, lateral drift they exhibited more brittle response yielding unforeseen damage during seismic excitations.

“…In general, the predisposition of a building to be damaged by a seismic impact depends on many aspects that are mainly concerned with the construction type, the quality of materials, the construction methods and the maintenance. Many studies [14][15][16] have shown how the lack of these issues makes structures inefficient so as to cause extensive damage during earthquakes. Indeed, the masonry buildings sample within the historical centres very often is characterised by a static inadequacy mainly due to an obsolete construction technique that does not guarantee an adequate safety standard.…”

The large-scale seismic risk assessment is a crucial point for safeguarding people and planning adequate mitigation plans in urban areas. The current research work aims at analysing a sector of the historic centre of Senerchia, located in the province of Avellino, in order to assess the seismic vulnerability and damage of old masonry building compounds. First, the typological classification of the inspected building aggregates is developed using the CARTIS form developed by the PLINIVS research centre in collaboration with the Italian Civil Protection Department. The global seismic vulnerability assessment of the building sample is carried out using the macroseismic method according to the EMS-98 scale in order to identify the buildings most susceptible to seismic damage. Furthermore, 12 damage scenarios are developed by means of an appropriate seismic attenuation law. Finally, the expected damage scenarios considering the local hazard effects induced are developed in order to evaluate the damage increment, averagely equal to 50%, due to the seismic amplification of different soil categories.The type of housing is called the "house on a slope". As in the second war, the population did not want to abate the use of building on the rock, even the second housing expansion along the Vallone river saw the buildings erected on the rocky coast [22]. The 1980 Irpinia EarthquakeThe Irpinia earthquake occurred on 23 November 1980 at 7:34 pm. A strong shock (X degree of the Mercalli scale) lasting about 90 s, with a hypocenter of about 12 km depth, striking an area of 17,000 km 2 that extended from Irpinia to Vulture, straddling the provinces of Avellino, Salerno and Potenza [23].The municipalities most severely affected by the earthquake were Castelnuovo di Conza,The type of housing is called the "house on a slope". As in the second war, the population did not want to abate the use of building on the rock, even the second housing expansion along the Vallone river saw the buildings erected on the rocky coast [22].
