Sponsored by the Infrastructure Resilience Division of ASCE In 2011, the Tohoku and Sendai regions on the east coast of Japan were devastated by the largest earthquake ever recorded in that country. The effects of the earthquake were immediately compounded by a massive tsunami that claimed thousands of lives, destroyed cities and towns, and severely damaged lifeline infrastructure. This report describes in detail the performance of lifeline systems in Tokyo, Tohoku, Sendai, and surrounding areas, as observed during multiple visits by an Earthquake Investigation Committee sent by ASCE’s Technical Council on Lifeline Earthquake Engineering (TCLEE). This TCLEE monograph discusses the following lifelines with recommendations for improving performance: transportation, electric power systems, telecommunications, airports, ports and harbors, water, wastewater, and gas and liquid fuel. General seismology of the event and geotechnical features of the area are described. Other relevant issues, such as debris management, effect on hospitals, fire following the earthquakes, emergency response, social impact, and lifeline interdependence, are considered. TCLEE 42 will be of interest to civil engineers, emergency managers and planners, and government officials charged with improving resilience of lifeline infrastructure systems during earthquakes and tsunamis.

Prepared by the Automated People Mover Standards Committee of the Standards Council of the Transportation and Development Institute of ASCE Automated People Mover Standards, ANSI/ASCE/T&DI 21-21, establishes the minimum requirements necessary to achieve an acceptable level of safety and performance for an automated people mover (APM) system. An APM is defined as a guided transit mode that is fully automated, featuring vehicles that operate on guideways with exclusive right-of-way. This standard covers design, construction, operation, and maintenance of APM systems. Topics include requirements for an APM in passenger operation, including chapters on security; system verification and demonstration; operation, maintenance, and training; and operational monitoring. One mandatory appendix covers requirements for system safety programs. Nonmandatory appendixes include a bibliography; recommended practice for acceptance of an APM system application; inspection and test guidelines; recommended practice for working safely near APM systems; and commentary on emergency egress provisions.This revision includes substantive changes and additions of mandatory requirements in a number of chapters. These include new requirements that address separation assurance for Automated Transit Networks (ATNs), revised requirements for the structural design of APM specific guideways, revised requirements for the application of safety provisions, and four new appendixes. This standard may be used in a safety certification process. It will be helpful to anyone who owns, operates, maintains, designs, tests, insures, oversees, or certifies APMs. It will also be valuable to transportation engineers, safety engineers, and contractors for APM systems or other innovative technology transit systems.

This committee report contains information on seismic exposure, design and installation practices that may be used to improve the seismic performance of communication systems. The suggested practices are born of years of design, analysis, equipment testing and installation, inspection trips, and post-earthquake reconnaissance surveys. While communication systems have been shown to be robust in comparison to other lifeline systems such as electric power and gas, a number of significant earthquakes have affected them since the San Fernando earthquake of 1971. The information in this report can be used to identify these vulnerabilities. It reviews methods for determining seismic hazards in different parts of the country; describes central office facilities and equipment, outside plants, and wireless systems; identifies each of the major elements that make up the facilities; and, finally, reviews the earthquake performance of these elements and recommended practices. With the coverage of these technical areas, this document can serve as a practical introduction to seismic engineering of communication systems or as a checklist by facility managers to assess the earthquake readiness of an installation.
