    Modifier parameters and quantifications for seismic vulnerability assessment of reinforced concrete buildings
    (2022) Oumedou, Amira; Lazzali, Farah
    In recent years, some studies have identified and quantified factors that can increase or decrease the seismic vulnerability of buildings. These modifier factors, related to the building characteristics and condition, are taken into account in the vulnerability assessment, by means of a numerical estimation resulting from the quantification of these modifiers through vulnerability indexes. However, views have differed on the definition and the quantification of modifiers. In this study, modifier parameters and scores of the Risk-UE Level 1 method are adjusted based on the Algerian seismic code recommendations and the reviews proposed in the literature. The adjusted modifiers and scores are applied to reinforced concrete (RC) buildings in Boumerdes city, in order to assess probable seismic damage. Comparison between estimated damage and observed damage caused by the 2003 Boumerdes earthquake is done, with the objective to (i) validate the model involving influence of the modifier parameters on the seismic vulnerability, and (ii) to define the relationship between modifiers and damage. This research may help planners in improving seismic regulations and reducing vulnerability of existing buildin

    Vulnerability assessment of an existing reinforced concrete shear wall building
    (2019) Oumedour, Amira; Lazzali, Farah
    The present study focused on assessing seismic vulnerability of an existing dwelling building with reinforced concrete shear walls, designed according to previous standards without seismic design. Firstly, visual inspection of the building is performed in order to identify defects, then, qualitative seismic vulnerability is assessed using existing methods. Finally, the compliance of the structure with some requirements of the current Algerian seismic regulations is examined.
