This paper deals with the application of the semi-probabilistic design concept (level I) to structural silicone sealants where a generally valid verification concept is proposed. The verification concept deals with the classification of silicone adhesive joints into cavitation-insensitive and cavitation-sensitive adhesive joints and at the same time advises which class of material models is necessary for the categorized adhesive joint systems. Furthermore, the static verification of a finite element based limit state analysis is shown within the design verification concept. The concept is elaborated and documented within this paper and illustrated by the help of an example. In the first part of this paper it was found, that the correct level I calibration of that partial material safety factors are significantly lower compared to currently existing estimates and thus allow for a great optimization of structural sealant design situations with potentially high economical as well as sustainability benefits.
