“…Their thickness and the density of steel bars increase with the height of buildings and the intensity of the earthquake. Shear walls take various forms such as T-shaped walls (Wang et al, 2023;Wang et al, 2022;Liu et al, 2023), U-shaped walls (Kim et al, 2023;Hoult and Beyer., 2021), and H-shaped walls (Silva et al, 2023). However, numerous studies have been conducted on L-shaped reinforced concrete shear walls (Gu et al, 2022;.…”

The Algerian Seismic Regulation of 1999, version 2003 (RPA99/v2003), presents ambiguities and a lack of thorough explanations in certain articles, which has led to a diversity of readings and interpretations among various stakeholders in the field, particularly the control offices. This situation has caused significant disagreements, especially during the approval of civil engineering files, thus resulting in a negative impact on project progress. To ensure adequate seismic protection of civil engineering structures, this work aims to unify the interpretations of certain passages of the regulation, with a particular emphasis on verifying the fundamental period of the structure, the shear forces at the base, and inter-story displacements using seismic calculation methods prescribed by the RPA. The comparative study demonstrates that no correlation between the period determined by the equivalent static method and that calculated by the spectral modal analysis method has been observed. This justifies the conclusion that adjusting between the empirical period and the dynamic period is not necessary.
