“…This period's educational infrastructure includes 9034 primary schools, 873 middle schools, 208 high schools and 32 university centers. Most of these constructions, with different typologies, are in a deteriorated state due to aging and poor maintenance, representing 30% of the educational system [5].…”

“…In this regard, the study of seismic scenarios allows decision-makers to adequately estimate the probable damage to structures designed using previous versions of seismic regulations or without seismic codes, as well as those constructed according to new seismic codes [4]. Therefore, the calculated damages by simulating seismic scenarios using the RISK-UE method are based on the definition of the general sources of seismic vulnerability of constructions [5].…”

“…In order to preserve the educational infrastructure in the city of Mostaganem, this study aims to assess the seismic risk by estimating the seismic vulnerability of reinforced concrete buildings. In this context, several advantages related to the RISK-UE method are significant in terms of the expected functional damages, which should undoubtedly concern the local authorities and necessitate rehabilitation and strengthening works for the school buildings [5]. The results obtained using this methodology form a database describing the probable damages to school buildings, which are presented and integrated using a GIS environment.…”

The present work aims to assess the large-scale seismic vulnerability of a set of 55 reinforced concrete educational establishments of different typologies (approximately 516 constructions) located within the urban perimeter of the city of Mostaganem. Among them, 328 buildings were constructed in accordance with the Algerian seismic regulation (built after 1980), while 188 constructions were built without a seismic design code (built before < 1980). This classification corresponds to the application/creation of this regulation following a major earthquake in Chlef (El Asnam) in 1980. Using the RISK-UE lm1 method, the vulnerability index was assessed based on a visual inspection for each building using an on-site inventory form to determine the general sources of seismic vulnerability. This strategy allows the prioritization of constructions according to their typologies, considering the structural system of the building and modifying factors, such as code level, maintenance condition, number of floors, plan and elevation irregularities, soil morphology, etc. The application of this methodology generated several seismic scenarios expressing the probable damage to the constructions, and the following results were suggested: The first two seismic scenarios have no damage corresponding to intensities I = 5; 6. The third scenario is characterized by low to negligible damage corresponding to intensity I = 7. Moderate damage was observed for the fourth seismic scenario (I = 8), while the fifth scenario generated by seismic intensity I = 9 presents moderate to heavy damage. The sixth scenario, with intensity I = 10, exhibits a relatively heavy damage balance. Starting from intensity I = 11, the damage becomes heavy to very heavy for the seventh scenario. Finally, the eighth scenario describes total destruction of the constructions. The results obtained from the application of this methodology on the educational buildings have been integrated into a Geographic Information System (GIS) environment to better understand the seismic behavior of the structures and to estimate the magnitude of seismic risk. This facilitates simulation and enables efforts to be made to take concrete preventive measures to strengthen existing educational buildings, thus reducing the negative impact of future earthquakes.

“…• The Boumerdès earthquake in 2003, with a magnitude of 6.8, caused the collapse and damage of many bridges, leading to the isolation of certain areas, disruption of basic services, and leaving behind human losses exceeding 2287 deaths (Sabeur et al, 2023). Bridge damage and collapse result in road closures, isolation of areas and cities, disruption of transportation and commerce, and even difficulties for emergency and security interventions.…”

Algeria is located in an active seismic zone, making its bridges vulnerable to damage, especially older ones. Due to the importance of bridges in terms of safety, social, and economic factors, competent authorities must prepare for disasters, particularly earthquakes, by enhancing bridge resilience. However, due to the large number of bridges and lack of funding, it is not feasible to improve all bridges at once. This article proposes a model to determine priorities for enhancing bridge resilience to earthquakes based on expert opinions in three main steps. Step 1: Identification of key criteria, where design phase, bridge health, seismic zone, bridge importance, availability of alternative roads, and disaster insurance are defined as key criteria. Step 2: Calculation of criteria weights using the analytic hierarchy process (AHP) and integration of expert opinions using the Euclidean distance-based aggregation method (EDBAM). Step 3: Calculation of the priority index after evaluating criteria categories. The model was applied to six bridges, and their ranking was established based on the priority index. The model has proven its accuracy and ability to assist decision-makers in identifying priority bridges.

“…Algeria has experienced several violent earthquakes in recent years, some of which were very devastating, such as the El Asnam earthquake of 1980 (Ms = 7.3 and intensity MMI = X), which caused more than 3000 deaths, 8369 injuries, 20,000 buildings destroyed and more than 480,000 homeless, and Boumerdes in 2003 (Ms = 6.8; MMI = X) with a balance sheet of 2287 deaths, 1000 injured, 19,000 buildings destroyed and more than 100,000 made homeless. The recording of the Boumerdes earthquake is used in the simulation of the seismic behavior of the minaret of the mosque, which is the objective of our work [2,3]. It is necessary to continuously monitor the health of buildings in order to detect damage or to locate areas that need to be rehabilitated.…”

Existing seismic vulnerability has become a topical of actuality, concerning both new and old buildings. Several techniques have been used to allow structures to better resist seismic events. In recent years, these have been so-called intelligent materials such as shape memory alloys (SMAs) due to their superelasticity and their ease in returning to their initial state after deformation, which can reach 10%. In the present article, nickel–titanium SMA is considered in a minaret of an old church transformed into a mosque to control the seismic response in terms of displacements, stresses and accelerations. The assessment of the seismic behavior was performed based on a modal and then transient analysis with Ansys software. The main objective was to determine the effectiveness of the addition of shape memory alloys by varying their number.
