This paper aims to
indicate the behavior of self-anchored suspension bridge (Pylon-Girder and
Cables) for prestressed concrete girder type when the main span increases from
160 meters up to 500 meters while monitoring the impact of this increase on the
bridge components, the increment process is done using scaling method as all of
the bridge geometrical properties and components dimensional properties are
selected relative to the bridge main span which allow for feasible comparison,
bridge reference model has been selected in accordance of other bridges
geometries which are implemented of the same type and initial calculation was
done for the components cross sections to eliminate the possibility of
selection errors and choose the most proper sections, the results clarify that
the bridge components behavior under dead and live load is linear with
increasing the span which mean that the validated dimensions proved to be
efficient, the prestressing system is important in order to control the stresses
at girder and keep them at allowable range which indicated the difficulty of
reaching this limit of spans using a reinforced concrete girder.
