Lebenszykluskostenbetrachtungen für chloridexponierte Bauteile von Brücken‐ und Tunnelbauwerken

Abstract: An Verkehrsbauwerken mit nur sehr geringem Alter sind in der Vergangenheit vermehrt Schäden aufgetreten. Ursache ist die hohe Chloridbelastung durch Streusalz/Sole aus dem Winterdienst, welche chloridinduzierte Bewehrungskorrosion hervorruft. Die Instandsetzung resultierender Schäden ist nicht zuletzt aufgrund in der Regel erforderlicher Verkehrssicherungsmaßnahmen sehr kostenintensiv. Immer öfter stellt sich die Frage, welche Maßnahmen zu ergreifen sind, um zum einen Kosten zu reduzieren und zum anderen aber … Show more

“…For each of the studied cases, as described in Section 2.4, the costs of the interventions in the future were calculated with an interest rate capitalization ( q 1 = 1.03) and an interest rate inflation ( q 2 = 1.02). The costs were calculated with the following formula, obtained from Reference 5: Kgoodbreak=KEgoodbreak+i=1n()()Ktgoodbreak+KVgoodbreak×q1tgoodbreak×q2t with costs of new construction K E , costs of intervention K t at time t , and costs of traffic interruption and construction site installation K V . For simplification K V was assumed as a global percentage of the costs of intervention.…”
