“…Seismic intensity degrees for the five most populated cities in Croatia, as given in 1950 [17], 1982 [18], and 1990 [18] Table 2. PGA (peak ground acceleration) values corresponding to the 1990 maps [19] for the return periods equal to 100 and 500 years, as well as the PGA values shown in most recent official seismic hazard maps for Croatia [8,9]. Here, we should note that none of the newest maps consider the features of the deeper geological formations beneath the sites, while the intensity degrees shown on all previous maps correspond to an average ground type and average deeper geological conditions.…”

“…The devastating power of seismic events exposes certain weaknesses in urban environments, as seen in recent earthquake- In order to reduce the impact of earthquakes on engineering structures, a logical approach and an assessment of earthquakes' effects on buildings-and more importantly, on people-is needed. With this aim, various methods were developed to estimate earthquake risk as accurately as possible [7][8][9]. An earthquake's risk is measured in its potential damage to buildings and other structures, as well as the number of people expected to be injured or killed in the area under observation.…”

Due to increases in the number of inhabitants and their concentrations in densely populated areas, there is a growing need in modern society to be cautious towards the impact of catastrophic natural events. An earthquake is a particularly major example of this. Knowledge of the seismic vulnerability of buildings in Europe and around the world has deepened and expanded over the last 20 years, as a result of the many devastating earthquakes. In this study, a review of seismic risk assessment methods in Croatia was presented with respect to the hazard, exposure, and vulnerability of buildings in the fourth largest city (Osijek) in Croatia. The proposed algorithm for a detailed risk assessment was applied to a database and is currently in its initial stage.Sustainability 2020, 12, 1796 2 of 24 to estimate the losses. These losses can be assessed in a material form, through the damage of the building stock or non-structural elements of buildings, or in the form of casualties or injuries during the earthquake [10,11]. The last step is to analyze uncertainties, costs, decision-making criteria, etc. The ultimate goal of studying earthquakes and their impact on people and buildings is to create a safer environment, in case an earthquake occurs.The basic elements of the earthquake risk assessment process are shown in Figure 1.Sustainability 2020, 12, 1796 2 of 25 probable intensity in a given geographical area). Then, based on the available data from the exposure model, evaluate the damage using one of the existing vulnerability assessment methods in order to estimate the losses. These losses can be assessed in a material form, through the damage of the building stock or non-structural elements of buildings, or in the form of casualties or injuries during the earthquake [10,11]. The last step is to analyze uncertainties, costs, decision-making criteria, etc. The ultimate goal of studying earthquakes and their impact on people and buildings is to create a safer environment, in case an earthquake occurs. The basic elements of the earthquake risk assessment process are shown in Figure 1.

“…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.

“…The evaluation of regional earthquake vulnerability is a basic concept in hazards research and a critical step in earthquake planning, prevention, and mitigation. Assessing regional vulnerability to earthquake is a complex problem that involves many factors, such as population density, economic development, average age of buildings, average height of buildings, earthquake intensity, quality of building materials, and lifeline systems [4][5][6][7][8][9][10]. In this study, preference is given to either smartphones or QR, which is a popular coding technology and one of the fastest ways to get information through efficient use of contemporary technologies for buildings in earthquake-prone regions.…”

The possibility of creating an "ID card" for each new and existing building in urban areas, based on transfer of necessary data into electronic format, is analysed in the paper. Local governments, public institutions, organizations, and building owners are thus able to obtain parametric information about the building using smart phones or tablets. Thanks to QR application, the access to building Inventory under seismic impact has become extremely fast and easily accessible via smart phones and tablets. The proposed IOS/ Android system greatly reduces the need to go through administrative formalities to obtain information and documents relating to an earthquake-prone building.
