✦ Synopsis
In steel structure design code-checking according to Eurocode 3 is a comprehensive task. Checking of resistance and classi®cation of cross-sections needed for the determination of the type of frame analysis (elastic, plastic) and the cross-sectional strength is especially complex. However, eective application of these rules is a problem due to complexity and inaccessibility of the rules. This leads to misunderstanding and misinterpretation by designers. Further, rules seem to be incomplete and inconsistent.
This paper describes a knowledge based system approach for checking completeness and consistency of rules in Eurocode 3 and for improving the accessibility of these rules. In order to realise this we use the conceptual modelling language Decision Tables'' to model the rules and the conceptual modelling tool AKTS'' to draw and access the decision tables. Decision tables clearly demonstrate incompleteness and inconsistency of knowledge. AKTS enables us to model knowledge in decision tables and to access this knowledge. This makes Decision Tables and AKTS an excellent combination for the development of a knowledge based system to support a complete and consistent resistance check and classi®cation of cross-sections in steel structures according to Eurocode 3.
