SEISMIC ASSESSMENT ANALYSIS OF BRIDGES IN MEXICO
In spite of the high seismicity of the country, a large number of existing bridges in Mexico were designed with non seismic provisions. Then, a methodology for the seismic evaluation of these structures is proposed. The assessment procedure is divided in two stages: the first involves a general screening study for the identification of the bridges in the worst conditions of vulnerability; the second stage is a displacement based procedure based on a capacity curve obtained with a non-linear static analysis. The results obtained with the proposed methodology have been compared for existing bridges that suffered different damage levels in past earthquakes and good correlation was observed. It is expected that the procedure will contribute to mitigate the seismic hazard posed by existent bridges.
