Optimization of management strategies applied to the national reinforced concrete bridge stock in France
The increasing age of national highway bridge stocks demands novel management policies that can maintain or increase safety levels in the light of reducing and budgets from the government. The French Highways Agency uses its Image Qualite Ouvrages d'Art - Structural Quality Imaging (IQOA) inspection programme to determine the conditions of its brid...
Non linear finite element analysis of a 50 years old reinforced concrete trough bridge
In this paper, a nonlinear finite element model of a full scale bridge (Örnsköldsvik bridge, Sweden) is presented in connection with load tests. In order to quantify the carrying capacity of the bridge, a collapse load test was performed within the European Union founded project "Sustainable Bridges - Assessment for Future Traffic Demands and Longe...
Vers une évaluation des indicateurs de durabilité du béton pour le suivi de ses dégradations en laboratoire et sur ouvra...
Cet ouvrage s'intéresse à l'évaluation des indicateurs de durabilité du béton ainsi qu'au suivi et à la prédiction de l'évolution des dégradations physico-chimiques, d'abord par des méthodes destructives puis non destructives. Une première partie est consacrée à la durabilité des ouvrages vis-à-vis de la carbonatation couplée au séchage suivant une...
The RILEM guidance on appraisal and management of structures damaged by AAR
The guidance made by a working group of the RILEM Committee TC 219 is dealing with the appraisal and management of structures damaged by AAR. This document is organized in four main chapters : a chapter on the effects of AAR on material and properties, a chapter from diagnosis to appraisal of residual structural capacity, a chapter devoted to the p...
Eliminating Alkali-Aggregate Reaction from long-service structures
RILEM has developed a testing and specification system to minimise AAR damage risk in new concrete structures. A performance test is being developed for particular mixes, usable on a project-specific basis; the challenge is proving a consistent relationship between test and field behaviours. Long-service structures, including dams, can sometimes ex...
