Part II : Lifelines. Chapter 12 : Standards for lifelines

In this chapter the status of standards and guidelines for the seismic safety of existing and new lifeline systems is described to provide a framework for end users who are presently collaborating on a national study to plan for the development and adoption of seismic guidelines and standards for lifelines. Although nationally recognized seismic standards are not yet available for all lifelines, advances are being made for: a) electrical power systems, b) gas and liquid fuel systems, c) telecommunications systems, d) transportation systems, and e) water and sewage systems.(AU)
