Seismic Assessment of a Masonry Structure Damaged by Central Italy Earthquake

Abstract

The present work shows the seismic vulnerability analysis of a building located in Matelica, a village that has reported extensive damages, especially to the monumental historical structures, after the Central Italy Earthquakes. The building is studied with local and global analysis, these last are performed using accurate 3D Finite Element Models where the post-elastic behavior of masonry is considered by the Total Strain Crack Model. The study showed as the use of non-linear static analysis, in addition to be useful to evaluate the seismic capacity, can reproduce with good approximation the cracks provoke by the quakes. After the estimation of actual capacity, the improvement of a seismic retrofitting intervention is evaluated
