    Algerian seismic code improvement by proposition of a specific design spectrum for Algiers City
    (Université de M'sila, 2020) Ibrahim Berra; Abderrachid Boulaouad
    This paper is an involvement in the improvement of the Algerian seismic regulation (RPA) which presents many deficiencies. Investigations are focused on the so-called “spectral modal analysis” (SMA) method commonly used for seismic evaluation. The applications are made on reinforced concrete structures in both cases: self-steady frames and structures with shear walls (bearing walls). Furthermore, comparison is made with time history (TH) method based on a number of recent Algerian seismic records. This work led to the proposition of a more accurate design spectrum specific to Algiers City usable in the classical (force) method as well as in a simplified “performance-based” method.
