Linearly elastic seismic evaluation of masonry historical buildings in Santiago, Chile : The case of the Pereira Palace

Abstract

Seismic assessment of the Pereira Palace by means of linear elastic analysis using finite elements techniques is the purpose of this work. Three static analysis based on the provisions of the current Chilean seismic code were performed, along with modal spectral and time-history analyses (responsespectrum-compatible records). Aiming to obtain from the analysis the same shear strain distribution and the current deteriorated building conditions, acceleration records experienced by the building on February 2010 were also used. Maximum shear stress obtained on the masonry elements were compared against an experimental value obtained from an in-situ test. The results obtained provide a first approach to the diagnosis of the building performance while proving the limitations and gaps on the current codes with respect to the seismic evaluation of these types of buildings.
