Seismic Awareness: Transportation Facilities. A Primer for Transportation Managers on Earthquake Hazards and Measures for Reducing Vulnerability Plus Appendices

摘要

The purpose of the report is to alert managers and operators of transportation enterprises, in both the public and private sector, to the dangers of earthquakes to buildings and possible precautions to be taken. The nature of seismic hazards in the U.S. is described. These include the probability of occurrence of an earthquake in a given area, as well as its likely intensity. The probable effects of earthquakes on particular structures (vulnerability) are examined. Vulnerability is dependent on the nature of the structure and local geology as well as seismic severity. The history and current practice of structural design to counteract seismic phenomena are given and retrofit practice is discussed.
