Étude comparative de deux structures élancées (portiques Auto-stable+ portique contreventé par des voiles)

Abstract

In this project, we studied the parametric seismicity of two slender structures (self-supporting gantry and walled bridge span) in reinforced concrete located in the third seismic zone. The calculations were carried out in accordance with Algerian regulations: RPA2003 rules. We model the two structures using a finite element calculation software, in order to perform a modular analysis and a seismic calculation for each structure in order to verify the dynamic stability. The results extracted from the calculation program made it possible to verify the stability of the structures, span, displacement, shear resistance, deflection, distribution of seismic forces, and to study the structural elements (columns, walls, beams) and the foundations in order to compare the results obtained in the two structures
