- Abstract
- Overall aims of this research are to develop a systematic way of assessing the adequacy and vulnerability of water/sewer distribution systems subjected to seismic loads, and also to develop future design methodologies for water/sewer systems. This paper presents state of the art information on the behavior and design of buried lifelines such as submerged tunnels, gas, water, and sewer distribution lines subjected to earthquakes. Specifically, a survey of pipelines damage due to past earthquakes as well as current design practices, analysis procedures, code provisions, and the latest published research are discussed.
