Course Length: 1 Hour
Purpose and Background
Failure of water transmission and distribution pipeline systems has been the primary cause of water system collapse in earthquakes. Lack of water for fire suppression following earthquakes has resulted in conflagrations. The pipeline network has historically been the primary cause of system failure.
The webinar will provide background information to allow participants to identify vulnerable pipe, discuss approaches to mitigate damage in existing systems, and design new piping systems that will be resistant to earthquakes.
The webinar will review historic system failures in earthquakes focusing on the components that caused the failures. Geologic/geotechnical conditions that lead to failures will be discussed. Pipe damage mechanisms and pipe vulnerability by pipe type will be developed and pipe vulnerability to earthquakes will be ranked. Finally, the preferred pipe materials will be recommended as well as design layout and detailing that will help mitigate earthquake damage.
Learning Outcomes/Benefits
- Learn about past performance of water systems in earthquakes
- Understand geologic and geotechnical conditions that affect pipeline performance
- Understand pipe damage mechanisms
- Learn about pipe vulnerability prioritization
- Learn approaches for earthquake mitigation of existing systems
- Learn how to plan and design new seismically resistant systems considering pipe selection, layout, and detailed design
Intended Audience
Civil and environmental engineers responsible for planning, design, and operation of pipelines will benefit from this webinar. Those responsible for maintaining the reliability of their water systems at a policy level to those responsible for day to day operation would also benefit from this webinar.
