Rehabilitation of Sidi M'Cid Suspension Bridge, Algeria
|Ausgabe:||Structural Engineering International", November 2000, n. 4, v. 10|
The structural rehabilitation of the Sidi M'Cid suspension bridge in Constantine, Algeria, is presented. The bridge, designed by Arnodin in 1908 has a main span of 160 m and a mixed cable-supporting system with a stayed deck portion near the towers. Over time various components of the bridge had corroded, calling for structural rehabilitation that included partial replacement of the main suspension system as well as major interventions on both anchorages. Because the bridge spans a canyon 200 m deep, specifically designed equipment was required in order to partially replace the suspension system while maintaining the bridge under full service.
