Resumen:

In Mexico, the free toll federal highway network has a length of more the 45,000 km and usually highways bridge design follows the American Standard Specifications for Highway Bridges. Oaxaca, Guerrero, Michoacan, Colima and Mexico State, are located on a potentially seismic zone and many bridges there have been designed without any seismic consideration. More than half of bridges in these Mexican States were designed and constructed between 1940 and 1970, with a structural type and design loads typical for those years. In addition, increased traffic demand and physical deterioration makes mandatory an extensive revision and generation of cost-effective strategies to protect and maintain those bridges. In this paper, a bridge classification based on construction year, substructure type and number of spans is presented. © 2012 Taylor & Francis Group.
