- Abstract
- The objective of the study was to develop a methodology to evaluate and apply retrofitting procedures to provide seismic protection to existing water systems in the United States. The report is concerned with the seismic protection of existing water lifeline systems (i.e., post-construction measures). The study includes a review of historical data on water system damage and failures caused by earthquakes. Existing codes and seismic evaluation methods for building and/or utilities were reviewed for application to existing water systems. Potential retrofitting techniques and associated preliminary designs are identified. Emphasis is on the utilization of the existing state-of-the-art knowledge of earthquake forces to develop a methodology for evaluating water system impacts and identifying methods to mitigate or minimize damage to critical systems.
