The Need for Qualitative Changes in Design Standards is Coming

Abstract eng:
A review of the increasing complexity of existing standards (Codes) for structural design shows that a disparity exists between them and the increasingly sophisticated assessment process that utilizes the full potential of computer technology. A qualitative change in the arrangement of standards is proposed, especially considering the transition from deterministic and “prescriptive” (allowable stress, e.g.) to probabilistic (such as Simulation Based Reliability Assessment - SBRA, see [1],[2]) methods; the basic standards should define the “rules of the game”, the secondary ones should deal with commonly occurring situations and the supporting standards and codes should supply extensive computerized databases. Creating such a hierarchical system of standards can reduce the present standards to the essential truths, and make the engineer free for conceptual problems.
