TS ISO 8930

TS ISO 8930 is a vocabulary standard for the core terminology used in structural reliability. It brings together the principal terms used when discussing the design and assessment of structures, helping authors and engineers use concepts such as actions, resistance, limit states, and reliability in a consistent way across related documents.

Common terminology for structural reliability

According to the scope, this document establishes the shared vocabulary used in ISO TC98 documents on bases for design of structures. In general technical terms, structural reliability refers to the ability of a structure to perform its intended function over time under expected actions and environmental influences. Design actions are the general class of loads, forces, and other effects considered in structural design; clearly distinguishing these terms is essential for reading design rules, probabilistic concepts, and performance-based language correctly.

Why a vocabulary standard matters

A terminology standard does not prescribe a calculation method on its own; instead, it provides the conceptual language that makes technical requirements easier to interpret consistently. In practice, that shared language supports design codes, research papers, specifications, and reports by reducing ambiguity and keeping structural engineering communication aligned. Its value lies in clarifying the foundation on which design principles are built.

• Shared terminology for structural reliability concepts
• Aligned language for ISO TC98 design basis documents
• Clearer distinctions between actions, resistance, and performance concepts
• Consistent interpretation of technical terms across related documents
