Resumen:

Cable Stayed Bridges have been built rapidly increasing numbers since 1950 and have been found to be especially economical for medium to long-span bridges from 100 to 1000 meters, where technical and economic considerations dictate a cable stay solution. The use of stay cable bridges in Mexico has been expanding in the last 20 years; today already exist more than 10 cable stayed in Mexico. Corrosion of steel is complex phenomenon affected by many environmental factor, the location of this bridges are around of the country (sea zones, high humidity zones, etc). Many bridges over 20 years show deterioration due to corrosion, As these bridges age, they need for effective inspection and maintenance, methods and tools becomes more acute. The aim of this study is to examine the effects of the corrosion phenomenon on the cable-stayed bridge Jaime Dovali Brigde evaluating by Non Destructive Test using electrochemical techniques and structural parameters. Dovali Bridge has a total length of 1170 m and a main span length is 288 m, this bridge where built in 1984, and is located about 20 kilometers from the Mexican Gulf. © 2012 Taylor & Francis Group.
