ABSTRACT
This chapter provides an overview of the standard ISO2394:2015 from the perspective of geotechnical engineering application. In addition to providing the context for Annex D, it summarises the overall features of the normative standard and the informative annexes, with emphasis on the advances incorporated in the 4th edition of ISO2394. As background the general role of the standard in reliability-based design is summarised. The historic development since the publication of the 1st Edition in 1973 provides a perspective on the legacy of the standard and the objectives set for the latest edition. An overview of the main components of the standard is presented next: consisting broadly of the two parts of the normative standard, firstly of basic principles and secondly the principles for applications. This is complemented by informative annexes that provide further guidance on implementation. The relevance of the standard and the balance of annexes is subsequently interpreted in general terms from the perspective of geotechnical structures; followed specifically in terms of the link to Annex D. The chapter concludes with a summary of the strengths and challenges for the advancement of reliability-based geotechnical design on the basis of the principles presented in ISO2394.
