Abstract:
This paper studies the minimum-cost strengthening of masonry arch railway bridges through optimal attachment of Fiber-Reinforced Polymer (FRP) sheets together with jacketing by reinforced concrete and shotcrete measures. For this aim, the Sahand-Goltappeh bridge, as a case study, is studied subjected to ordinary train pass. Finally, the strengthening cost is minimized pursuing following goals: i) the bridge s load-carrying-capacity is increased; and, ii) the response values of the bridge are reduced to a certain limit. The strengthening cost is estimated based on Iranian prices list for railway construction services. The results show that strengthening costs can be reduced by optimal utilization of FRPs.
