What is ISO 16134 about?
ISO 16134 specifies the design of earthquake-resistant and subsidence-resistant ductile iron pipelines suitable for use in areas where seismic activity and land subsidence can be expected. ISO 16134 provides a means of determining and checking the resistance of buried pipelines and gives example calculations. It applies to ductile iron pipes and fittings with joints as specified in ISO 2531, ISO 7186, and ISO 16631 that have expansion/contraction and deflection capabilities, used in pipelines buried underground.
NOTE: Subsidence is not the effect of an earthquake or a sinkhole.
Who is ISO 16134 for?
ISO 16134 on earthquake-resistant and subsidence-resistant design of ductile iron pipelines is relevant to:
- Seismologist
- Manufacturer of ductile iron pipelines
- Civil engineer
- Architect
Why should you use ISO 16134?
Buried pipelines are often subjected to damage by earthquakes. It is, therefore, necessary to consider earthquake resistance, where applicable, in the design of the pipelines. In reclaimed ground and other areas where ground subsidence is expected, the pipeline design must also consider the subsidence.
ISO 16134 provides information on earthquake-resistant design, design for ground deformation by an earthquake, design for ground subsidence in soft ground, pipeline system design.
As the user of ISO 16134, you can determine and check the resistance of buried pipelines in areas where seismic activity and land subsidence can be expected. ISO 16134 assists the user in designing a safe earthquake-resistant pipeline system that is not affected by any ground deformation. ISO 16134 limit economic loss during an earthquake. Overall the main objective of ISO 16134 is to design, build and maintain a ductile iron pipelines system that can withstand earthquakes.
What’s changed since the last update?
ISO 16134 supersedes BS ISO 16134:2006, which is withdrawn.
The main changes compared to the previous edition are as follows:
- The classification of pipelines components in Table 3 is modified;
- The relationship between seismic intensity and ground surface acceleration in Table B.1 is modified;
- The calculation method of checking the safety of the pipeline against ground deformation is added in 5.3.
