Durability design of concrete structures—Committee report 130-CSL

The idea of the durability design of concrete structures is developed as statistical theory which is based on the probability of failure taking into account the time as a parameter of the performance function and of the loading function. The generalised loading includen environmental effects into the structure like mechanic loading and weathering (sun, temperature changes, frost, moisture, pollutants, oxygen etc.). As generalised capacities like loading capacity, tightness, deflections, cracking, smoothness of the surface and visual fitness are treated. The statistical theory is transformed into practical deterministic durability design applying partial safety factor method. Important addition into the ordinary partial safety factors is the lifetime safety factor which is introduced into a design for first time here. The static and dynamic performance parameters and the durability performance parameters are combined together in the final phase of design. Performance and service life calculation models is introduced into design method, and presented for six decradation processes. The article is based on the report of RILEM TC 130—CSL [31], where the author was serving as chairman.

La notion de durabilité des constructions en béton est développée ici comme une théorie statistique basée sur la probabilité de rupture prenant en compte la donnée temporelle comme un paramètre de la fonction de performance et de la fonction de chargement. Le chargement généralisé comprend les effets environnementaux dans la construction tel que le chargement mécanique et les effets des intempéries (exposition au soliel, écarts de températures, gel, humidité, polluants, oxygène, etc.). Lorsque les capacités globales telles que les capacités de chargement, l'étanchéité, la flexion, la fissuration, la douceur de la surface et l'aspect visuel ont été traitées, la théorie statistique est appliquée dans une démarche de conception pratique et déterministique de la durabilité, mettant en œuvre un facteur partiel de sécurité introduit ici pour la première fois dans la conception. Les paramètres de performances statiques et dynamiques et les paramètres de performances de durabilité sont associés dans la phase finale de conception. Les modèles de calcul de performance et de durée de vie sont incorporé aux méthodes de conception, et présentés pour une série de six processus de dégradation. L'article est basé sur le rapport de la commission technique RILEM TC 130_CSL: ‘Calculation methods for service life design of concrete structures’, qui était présidée par l'auteur du présent rapport.
