“…On the basis of the probability mass function of the binomial distribution, the probability of having damage, P(D k ), which is a statistical demonstration of DPMs, is calculated with Equation ( 7) [94,102,103]. For various damage grades, the fragility curves consist of the y − axis (P[D k ]), which is shown in Equation ( 8), and the x − axis (I EMS−98 ) [102]:…”

“…Giovinazzi [92], Giovinazzi and Lagomarsino [93], and Lagomarsino and Giovinazzi [88] made further developments in the macroseismic model, which uses classical probability theory and fuzzy set theory in order to determine the vulnerability of buildings on the basis of the EMS-98 in European areas [11], as explained by Gueguen [85]. Ademović et al [94] conducted an assessment on the seismic vulnerability of existing masonry buildings in Bosnia and Herzegovina in 2020 using the macroseismic method adapted from the EMS-98 scale and the vulnerability index method (VIM). In Cologne, Germany, the EMS-98 [11] was used to demonstrate five possible vulnerability classes of the existing buildings using DPMs, on the basis of five damage states or fragility curves [95,96].…”

Developments in the field of earthquake engineering over the past few decades have contributed to the development of new methods for evaluating the risk levels in buildings. These research methods are rapid visual screening (RVS), seismic risk indexes, and vulnerability assessments, which have been developed to assess the levels of damage in a building or its structural components. RVS methods have been proposed for the rapid pre- and/or post-earthquake screening of existing large building stock in earthquake-prone areas on the basis of sidewalk surveys. The site seismicity, the soil type, the building type, and the corresponding building characteristic features are to be separately examined, and the vulnerability level of each building can be identified by employing the RVS methods. This study describes, evaluates, and compares the findings of previous investigations that utilized conventional RVS methods within a framework. It also suggests the methods to be used for specific goals and proposes prospective enhancement strategies. Furthermore, the article discusses the time-consuming RVS methods (such as FEMA 154, which requires from 15 to 30 min, while NRCC requires one hour), and provides an overview of the application areas of the methods (pre-earthquake: FEMA 154, NRCC, NZEE, etc.; postearthquake: GNDT, EMS, etc.). This review of the traditional RVS methods offers a comprehensive guide and reference for field practitioners (e.g., engineers, architects), and recommends enhancement techniques (e.g., machine learning, fuzzy logic) for researchers to be used in future improvements.

“…Throughout the history, earthquakes in Albania, like in many earthquake-prone countries in the region, have seriously affected built environment causing numerous human casualties and economic loses [3][4][5][6][7][8][9]. In this regard, buildings' vulnerability is a key concept to focus on to mitigate the consequences of seismic events.…”

After the earthquake, the inspection carried out by the authors in the region has provided relevant findings regarding the methods of construction, quality of the materials and the performance of structures. The dominant building types in the Albanian building stock comprise unreinforced masonry (URM) structures with load-bearing masonry walls. These units suffered the worst damage. Dynamic response of masonry is highly nonlinear, and generally shows high vulnerability to seismic loading. Moreover, many buildings of these type have undergone structural interventions like adding floors, or wall openings, especially in the first floors of the buildings, which are parallel to the main roads, because of great demand for shops and stores. This paper aims at making seismic performance assessment of the intervened buildings based on macro-element modeling approach. Due to its efficiency, this approach is becoming popular among the practitioners and field experts in this area and allows simulating the non-linear behavior of masonry buildings. This method is applied to two old masonry buildings from the Albanian construction practice that are representatives of mid-size residential buildings with and without interventions. It must be said that in Albania, masonry buildings have been built using templates all over the country, so both models with and without intervention are common. Capacity curves of the investigated buildings are derived to assess the most probable seismic response of the investigated housing construction in the region as well as to evaluate the seismic performance of the tested structures.

“…Recent reports, produced after the inspection of areas affected by strong earthquakes, have concluded that informally constructed reinforced concrete buildings responded with a low level of damage or did not collapse due to the contribution of the masonry [6]. Notably, it has been determined that the contribution of masonry is beneficial when the construction process is carried out with confined masonry structural systems, which present an acceptable performance even for modified Mercalli intensities between VIII and IX [7].…”

Irregularity of the Distribution of Masonry Infill Panels and Its Effect on the Seismic Collapse of Reinforced Concrete Buildings

et al. 2021

View full text Add to dashboard Cite

On 16 April 2016, an earthquake of Mw 7.8 shook the coast of Ecuador, causing the destruction of buildings and a significant number of casualties. Following a visit by the authors to the city of Portoviejo during the debris removal and recovery stage, it was noted that several reinforced concrete buildings located on corners had collapsed in the central part of the city. These buildings were characterized by the presence of masonry at the edges of the buildings but not between the two mostly open-plan facades on the corner for practical reasons. This article reviews the effect of masonry infill panels on the seismic response of reinforced concrete structures. For this, a model that contains the geometric and mechanical characteristics typical of collapsed buildings was generated and subjected to nonlinear analysis, with both static and dynamic increments. The results show the clear influence of the masonry infill panels on the structural response through the torsional behavior that is reflected in the evolution of the floor rotations. Finally, dynamic incremental analysis is used to obtain the collapse fragility curve of the building, and a new damage measure based on floor rotations is proposed.
