Earthquake Resistant Construction of Electric Transmission and Telecommunication Facilities Serving the Federal Government (FEMA-202)


FEMA Resource Record Cover Image Thumbnail – fema202cover.jpg This report summarizes a National Institute of Standards and Technology study that reviewed measures implemented by federal agencies to protect electric power transmission and telecommunication lifelines against seismic hazards. The report examines the seismic vulnerability of these lifelines and discusses current standards and design criteria. Seismic retrofitting techniques for components and systems are reviewed, including the benefits of retrofitting versus gradual replacement. A summary of federal practices in the design of new facilities and the retrofit of existing facilities is included.
