Full title and description

ISO 16134:2020 — Earthquake-resistant and subsidence-resistant design of ductile iron pipelines. This international standard specifies methods to determine and check the resistance of buried ductile iron pipelines to seismic actions and to land subsidence, and provides example calculations and design guidance for pipes and fittings with joints that allow expansion, contraction and deflection.

Abstract

ISO 16134:2020 gives design principles, calculation methods and verification procedures for buried ductile iron pipelines intended to remain functional (or to resist damage) when subjected to seismic events and to land subsidence. The document is written for ductile iron pipes and fittings with joints described in related ISO pipe standards and includes worked examples to illustrate the design checks.

• Publisher: International Organization for Standardization (ISO).

Scope

Applies to ductile iron pipes and fittings used in buried pipelines where seismic activity and/or land subsidence may occur. The standard defines how to assess pipeline resistance, provides calculation methods and example checks, and is applicable to pipe/joint systems that permit axial movement and angular deflection as specified in complementary ISO pipe standards. It does not treat subsidence caused by sinkholes as part of the earthquake effect note.

Key topics and requirements

• Design principles for earthquake-resistant buried pipelines (load definition and response considerations).
• Assessment of land subsidence effects and differentiation from seismic loading.
• Calculation procedures and worked example calculations for verifying pipeline resistance.
• Requirements and assumptions for ductile iron pipes, fittings and joint behaviour (expansion/contraction and deflection capability).
• Design checks for buried pipeline integrity, joint performance and allowable deflections.
• Guidance for combining geotechnical and structural considerations in pipeline layout and detailing.

Typical use and users

Used by pipeline design engineers (civil, structural and geotechnical), water and wastewater utilities, municipal infrastructure planners, manufacturers of ductile iron pipes and fittings, and standards committees. Typical applications include potable water, sewage and other buried pipeline systems in seismic or subsidence-prone regions where ductile iron systems are specified.

Related standards

ISO 16134:2020 references and is intended to be used with standards that define ductile iron pipe and joint characteristics, notably ISO 2531, ISO 7186 and ISO 16631. It replaces ISO 16134:2006 (withdrawn) and is maintained under ISO/TC 5/SC 2 (ductile pipes and fittings).
