Dauerhaftigkeit von Stahlbeton in Tunnelbauwerken - Einfluss von Baumängeln

Durability of Reinforced Concrete in Tunnels: Influence of Building Defects The present paper outlines the influence of deficiencies linked to reinforced concrete constructions on the durability. As requirements related to durability matters are in general defined by descriptive guidelines, the objective assessment of deficiencies and the dimensioning of necessary measures for retrofitting are hardly feasible. Whereas a definition of the durability of performance related requirements enables a new procedure to assess deficiencies more objectively. On this basis feasible measures can be chosen and dimensioned. In principle this introduced procedure can also be applied for the performance related assessment of the retrofitted structure.
