ASSESSMENT OF RESIDUAL LIFE OF GIRDERS OF BRIDGE No

scale ( fig.-5) and residual life for the actual operational traffic density of the
section, where these girders are likely to be used, can be obtained with the use
of this graph. Although, it is observed from the report prepared by the Railway
(Annexure-I) that many girders are having corrosion particularly in top flange
plates, but this factor is not considered in this study. Hence, it is advised that the
corroded parts of the girders should be replaced before their reuse.
7.0 Conclusions:
The girders of both the abandoned bridges can be used for traffic density of
27GMT for a period of about 60 years. With replacement of corroded parts, the
remaining life span of the girders can be extended further, if traffic density is less
than 27 GMT and good maintenance practices are being followed.
