Réduction de la vulnérabilité du vieux bâti par l’Analyse du comportement structurel face aux sollicitations sismiques à l’aide de l’outil informatique

Abstract

Seismic risk assessment of historical structures of old buildings has become an increasingly important subject, because of the high vulnerability of this heritage to the seismic risk. Our research aims to establish a numerical simulation on the mosque of old Tenes, in order to highlight the critical zones in this monument. This mosque was collapsed during the main shock of the 1954, Chlef earthquake on which the mosque underwent huge modifications, for this the structural analysis, was carried out at the base a modeling of the two models in order to study the behavior of the mosque before and after the earthquake. Response spectrum analyzes were performed to evaluate the seismic response of both structures; The numerical analyses is based on finite element modeling(FEM) using the Robot Structural analysis 2017 program, after which the results obtained have been interpreted to detect the different vulnerable zone un each model.
