Optimum Seismic Protection for New Building Construction in Eastern Metropolitan Areas. Incident Losses: Information Obtained from Los Angeles Field Trip, 14 January to 23 January, 1973

摘要

In studying future losses in high-rise buildings caused by earthquakes, both physical and non-physical costs have been considered. Since the latter remains in the conceptual stage, an effort has been made to identify causes or sources of these costs; i.e., incident losses, and to suggest evaluation methods for assessing them. This study attempts to establish the validity of these concepts by obtaining information from building owners, building occupants, and the public; and from their perception, modify previous descriptions of incident losses and propose revised evaluation methods. Interview questions (Appendix A) are structured to obtain information about earthquake related phenomena in the building, activities of occupants, incident losses perceived during the quake, during final repairs, and subsequent to final repairs. The report describes selection of interviewees, scheduling of interviews, and information obtained. Incident losses are summarized and conclusions are drawn from the information. Appendices include charts on the nature of information obtained, specific building data and descriptive paragraphs of observations made by building occupants.
