Seismic resilience assessment of buildings: case study of Blida city

Abstract

Several studies have been carried out to assess the building’s seismic vulnerability, in order to mitigate the seismic risk in urban areas, which is one of the most devastating natural hazards causing considerable economic and human losses. These studies must be incorporated to improve the planning of urban areas in order to have resistant and resilient cities in case of disasters. The seismic feedback has shown that the build back better concept has a direct impact on the city’s economic growth. In this paper, the existing buildings resilience is assessed, in order to highlight the capacity of these last to keep the functionality when an earthquake occurs. This building’s resilience has been determined according to the damages states, the reconstruction time and the reconstruction cost for three types of structures: masonry, reinforced concrete and steel. The vulnerability curves used give the damage grade according to the vulnerability index and the seismic intensity. A seismic resilience scenario was performed using a geographic information system (GIS) and applied for the Blida city (Algeria) classified as a high seismic zone according to Algerian seismic regulations.

Seismic Hazard Resilience in Montenegro: A Comprehensive Qualitative Analysis of Local Preparedness and Response Mechanisms

“…The structural integrity of heritage masonry buildings is undermined by poor craftsmanship and the absence of routine maintenance, heightening their risk during seismic events [28]. In regions with high seismic risk, such as Blida City, evaluations of building resilience often concentrate on vulnerability curves, states of damage, timelines for reconstruction, and related costs, all crucial for enhancing seismic resilience [29].…”
