in Figure 4.106 , while the steel plate girder cross section in the remaining
parts consists of an upper flange plate of 500 30 mm 2 , a web plate of
1740 16 mm 2 , and a lower flange plate of 700 30 mm 2 , as shown in
Figure 4.106 . The web plate is stiffened by vertical stiffeners spaced at 1.5 m
as shown in Figure 4.107 . The steel material of construction of the double-track
railway bridge conformed to standard steel grade EN 10025-2 (S 275) having a
yield stress of 275 MPa and an ultimate strength of 430 MPa. The bridge has
