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.
