Bridges with corrugated steel webs have been extensively
constructed in different countries. A trapezoidally corrugated
steel plate is composed of a series of longitudinal and
inclined subpanels. For a steel corrugated web girder, it is
assumed that the web carries merely shear forces due to the
accordion effect [1,2]. The web in such a girder was found to
carry insignificant longitudinal stresses from the primary
flexure. Consequently, the bending moment is nearly carried
by its flanges. Thus, it is worth pointing out that the shear
strength can be determined without consideration of
moment-shear interaction. But it was found that problem in
an area where intermediate supports that shear forces are
completely carried by web, and found that the value of the
shear resistance, which is a concrete slab by almost be
neglected. In recent years has been the study of different
types of materials to increase the efficiency of concrete and
increase the shear forces at the intermediate supports. Thus
in this research, the effect of adding fiber to the concrete in
composite corrugated plate girders at intermediate supports
was investigated.
