Seismic safety analysis of the old portuguese cathedral in Safi, Morrocco

Abstract

The paper presents the main results of the safety analysis of the Safi Cathedral. First a general description of the cathedral and the restoration project are given. To assess the safety of the main arch of this cathedral after the restoration, a seismic line of thrust analysis was used. The results of this uncommon analysis for structures which face seismic hazard were then compared to the results obtained from a phased pushover analysis. The results of the seismic line of thrust analysis turned out more conservative than those of the finite element analysis, although in both cases the results depend on the modeling hypothesis.
