Full title and description

St ISO TR 12930-2014 — "Seismic design examples based on ISO 23469". This Technical Report collects worked geotechnical seismic design examples (buried structures, foundations, retaining walls, pile-supported wharves and piers, earth and rock fill dams and embankments, gravity dams, tanks, landfill/waste sites, etc.) to demonstrate and guide application of ISO 23469.

Abstract

Provides detailed seismic design examples for geotechnical works based on ISO 23469:2005 to illustrate procedures for determining site-specific seismic actions and design approaches. The examples are intended as guidance for experienced practicing engineers and code writers and include deterministic and probabilistic ground motion evaluation, Fourier amplitude and time‑history considerations, and application to a range of geotechnical structures.

Scope

Demonstrates how to apply ISO 23469:2005 to perform seismic design for a broad set of geotechnical works by providing step‑by‑step examples. Coverage spans the first stage of seismic action specification (site-specific ground motions), deterministic and probabilistic seismic hazard evaluation, site amplification and Fourier spectrum assessment, selection and application of ground motion time histories, and detailed example calculations applied to common geotechnical structures. The examples are illustrative and intended to support engineers and code writers in interpreting and implementing ISO 23469.

Key topics and requirements

• Worked examples applying ISO 23469 procedures to buried tunnels, box culverts, pipelines and underground storage.
• Examples for shallow and deep foundations, diaphragm walls and retaining/quay walls.
• Site‑specific seismic hazard analysis: deterministic scenarios and probabilistic seismic hazard analysis with Fourier amplitude and group delay time evaluation.
• Evaluation of site amplification factors, uniform hazard Fourier spectra and generation/use of ground motion time histories.
• Application examples for earth structures (dams, embankments), gravity dams, tanks, pile‑supported wharves/piers, and landfill/waste sites.

Typical use and users

Used by geotechnical and structural engineers, seismic design specialists, consultants producing design reports, and code writers developing or updating seismic/geotechnical guidance. Also useful in academic and training settings to illustrate practical application of ISO 23469 procedures.

Related standards

Mainly related to ISO 23469:2005 (the normative reference on which the examples are based). It is produced under ISO/TC 98 (Bases for design of structures) — specifically SC 3 (Geotechnical aspects of structures). National seismic and geotechnical design codes are complementary and users should coordinate TR examples with applicable national regulations.

FAQ

Q: What is this standard?

A: ISO/TR 12930:2014 is a Technical Report that provides seismic design examples illustrating application of ISO 23469 for geotechnical structures. It is an informative collection of worked examples rather than a normative design code.

Q: What does it cover?

A: It covers step‑by‑step seismic design examples: site‑specific ground motion determination (deterministic and probabilistic approaches), evaluation of site amplification and Fourier spectra, generation and use of ground motion time histories, and worked applications to a range of geotechnical structures (foundations, tunnels, retaining walls, dams, tanks, wharves, landfills, etc.).

Q: Who typically uses it?

A: Practicing geotechnical and structural engineers, seismic specialists, consultancy teams preparing seismic design reports, and code developers seeking illustrative examples for applying ISO 23469. It is also used for education and training.

Q: Is it current or superseded?

A: ISO/TR 12930 was published in April 2014 (Edition 1) and is listed as "Published" in the ISO catalogue. There is no record on the ISO catalogue of a superseding edition or withdrawal as of March 2, 2026 (the date this information was checked). Users should verify the ISO catalogue or national adoption bodies for any updates after that date.

Q: Is it part of a series?

A: It is an informative Technical Report accompanying ISO 23469:2005 (the standard it illustrates). It is not a mandatory part of a numbered "series" but sits within ISO/TC 98/SC 3 work on geotechnical seismic design and related deliverables.

Q: What are the key keywords?

A: Seismic design, geotechnical design examples, site‑specific ground motion, Fourier amplitude, time history, foundations, retaining walls, buried structures, dams, tanks, landfill.
