Fig. 5. Cross-sections and measured corrosion losses of: a) the main girder of the read bridge A; b) the main composite girder of the bridge B on service road; c) the stringer in open deck of the railway bridge C; dimensions in millimeters.

The results of study are summarized in Table 2 and Figure 6, where the relative decrease of the cross-section area A , cross-section modulus W and the load-carrying capacity due to increasing corrosion losses during the service life of the bridges are presented. The load-carrying capacity of the chosen bridge members was determined from the elastic bending resistances of the cross sections.
