However, once a bridge is open to traffic and starts carrying its actual loads, it also starts to deteriorate. This is mainly because of environmental factors and increase in traffic load. For this reason bridge condition must be evaluated periodically to insure bridge safety under in-service ...
However, because of environmental factors (i.e. corrosion) and increase in traffic load, deterioration of bridge members are usually observed before the bridge reaches mid-life. Therefore the design cannot guarantee a life long safety. In order to insure the safety of the bridge under operating ...
