Abstract
Development of a partial safety factor for high strength grouts in offshore applications. During the design of grouted connections in offshore applications (wind turbines and platforms), the fundamental material interrelationships are derived primarily on the basis of DIN EN 1992 which is applicable to the design and construction of building of concrete, reinforced concrete and pre-stressed concrete. In the paper at hand the application of the design value for the compressive strength of concrete fcd to modern, high performance grouts is discussed. Firstly, the components of the design value for the compressive strength of concrete fcd are presented in detail and it is then discussed how in the safety concept within the standards variances are considered in the underlying assumptions and uncertainties are taken into account during their determination. Coefficients of variation were determined based on values of compressive strength from realistic and offshore-typical grouting experiments, which were applied during the determination of the partial safety factor for grout ΓG. The applicability of the design value of the compressive strength of concrete fcd under consideration of the derived partial safety factor for grout ΓG was subsequently tested and compared to the design value of DIN EN 1992.
