On the Design of Pipe Supports and Steelwork Regarding Revised German Nuclear Safety Standards

摘要

The design review of pipe supports is discussed in this paper putting the main emphasis on the stress analysis of weld seams. In the non-nuclear area, there has been made a change in the design concept for structural steelwork of surface constructions in Germany and the deterministic design concept of German DIN 18800 (03/81) [1] has been replaced by the semi-probabilistic design concept of DIN 18800 (11/90) [2]. The design concepts are compared which each other. Differences between the two standards [1] and [2] are investigated using an example of a simple steel construction. Results for dimensioning according to DIN 18800 (03/81) [1] are compared to those for dimensioning according to DIN 18800 (11/90) [2]. In former papers of the authors the effects on the steel profiles and building structure interaction loads are investigated. In this paper the authors are putting the main emphasis on stress analysis of weld seams.
