- 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. As a first step in developing a systematic way of assessing the adequacy of the Latham Water Distribution System to seismic excitation, this report determines the seismic risk of the Albany area. Richter's relationship and the average occurrence rate for the Albany, New York area is established from available data of earthquakes in the Northeast. The coefficients for the attenuation relationship is estimated by a search of current literature. A standard deviation of the error term in the attenuation relationship is varied and the resulting return periods and annual risk is compared with results obtained using a deterministic attenuation relation. Finally, using these parameters, recommended return periods and seismic risk for the Albany area are presented.
