Abstract

The study recommends revising the Algerian seismic code (RPA) by introducing a new design spectrum based on real seismic data. The current code has shortcomings that may lead to underestimating seismic forces, risking structural safety. The proposed spectrum aims to offer a more accurate assessment of building behavior during earthquakes and aligns with the globally recognized performance-based design approach. The revision includes updates to formulas and parameters, as well as recommendations for improving spectrum accuracy. By utilizing Algerian seismic data, this approach is expected to provide results more relevant than international standards like FEMA and Eurocode 8. This work seeks to incorporate these enhancements into the Algerian code, replacing traditional methods and providing better protection against seismic risks.
