“…Nonlinear time-history analysis (NTHA) is probably the most accurate method for seismic analysis of individual buildings. An alternative to NTHA is to adopt nonlinear static analysis (NSA), which is a less computer demanding alternative, often used for seismic assessment of school buildings [9,[18][19][20]. Moreover, the validation tests that were carried out upon the development of a dedicated seismic assessment software show a good agreement between NTHA and NSA [16].…”

The seismic assessment of existing school buildings is an important issue in earthquake prone regions; such is the case of the Algarve, which is the southern region of Portugal mainland. Having this problem in mind, the PERSISTAH project (Projetos de Escolas Resilientes aos SISmos no Território do Algarve e de Huelva, in Portuguese) aimed to develop a computational approach enabling the damage evaluation of a large number of individual school buildings. One of the school typologies assessed was the so-called “P3” schools. This typology is composed of several different modules that are combined in different manners depending on the number of students. Each module was built in accordance with architectural standardised designs. For this reason, there are many replicas of these modules all over the Algarve region. The structural system of each module is composed of a frame of reinforced concrete (RC) elements. Nonlinear static seismic analysis procedures were adopted to evaluate the structural seismic behaviour, namely by using the new concept of performance curve. Based on the obtained results, it was possible to conclude that the seismic safety of this type of school building is mainly ruled by the shear capacity of the columns. This study also shows the difficulties of carrying out accurate seismic assessments of existing buildings using the methods of analysis that are established in the Eurocode 8.

To determine the seismic performance of historical buildings  To develop a simplified method based on the displacement  To evaluate the performance of a historical mosqueIn this study, a simplified performance evaluation method is presented to determine the seismic performance of historical buildings. Besides, the earthquake performance of the historical Kaya Çelebi Mosque, which was damaged during the 2011 Van Earthquake, is examined using this evaluation method presented within the scope of the study. Figure A. Maximum lateral displacement (mm) on the minaret in the Z and X direction obtained from DD2 seismic hazar levelPurpose: The aim of this study is to develop a simplified method based on displacement in order to determine the earthquake performance of historical buildings. Theory and Methods:In the simplified method, the performance evaluation is carried out in the five main stages, which are Collecting Preliminary Information, Determination of Material Properties, Preparation of the Finite Element Model, Finite Element Analyses, Evaluation of the Numerical Results. Results:As a result of the evaluation, the minaret of Kaya Çelebi Mosque is very sensitive in terms of seismic and the displacement ratios obtained in the minaret in the Z direction. Conclusion:It is concluded that the "Simplified Assessment Method" proposed within the scope of the study can be effective in evaluating the earthquake performance of existing historical buildings and can be implemented in many different buildings.

“…This tendency may be linked to OECD's concern that the collapse of school buildings from around the world is caused by human induced failures, like avoidable construction and design errors, improper use of technology and lack of regulations enforcement [24], [25]. Some of the previous studies use methodologies adapted to fit the evaluation of seismic vulnerability of school buildings made out of a specific construction material [6], [10], [11], while others assess prototypes of school [5], [13], [14], [18]. For many of the mentioned papers, the key element is represented by fragility curves [6], [12], [15], [18] and the number of multicriteria-based approaches to the matter is rather low [23].…”

Multi-Criteria Assessment of the Seismic Vulnerability of School Units in Vaslui City, Romania

2020

In the context of an earthquake impact, school units are particularly vulnerable because of the specific age group of the population that studies there. This means that the earthquake mitigation strategies targeting schools should be carefully elaborated, starting from a proper assessment of their seismic vulnerability. Such assessments should be extensively conducted, especially in the case of urban settlements that are disadvantaged in terms of economic potential, social development and media image, like Vaslui City, Romania. This paper aims to evaluate the seismic vulnerability of school units in Vaslui City using a combination of Multi-Criteria Decision-Making (MCDM) methods and Geographic Information System (GIS) techniques. Unlike other assessments of this type, the proposed framework integrates both aspects related to the physical vulnerability of the school buildings, and social elements concerning the educational personnel, the age profile of the pupils, school hours and other factors. The methodology also includes a systemic vulnerability component that offers better insights about the access emergency services would have to the educational institutions in case of a powerful earthquake. The physical, social and systemic vulnerability factors/criteria are weighed via Analytic Hierarchy Process (AHP), while the 25 school units in the study area are evaluated using Weighted Product Model (WPM). The results are combined with GIS techniques in order to obtain a map that shows the seismic vulnerability level of the school units. The most vulnerable school units are the ones with tall old buildings located along narrow streets, with significant number of very young or disabled pupils. These findings represent the stepping stones for the retrofitting works and the educational programmes related to seismic hazards that should be implemented by local authorities. Although restricted by the low number of educational institutions in the study area, the proposed framework may be further on used in seismic vulnerability research.
