ABSTRACT: The purpose of this 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 !o counteract seismic phenomena are given and retrofit practice is discussed Economic considerations are evaluated, with emphasis on the cost effectiveness of building new reinforced structures versus retrofitting existing structures. Three appendices provide technical explanations of the material presented in the text proper.
