Assessment of Lifeline Response and Recovery Performance Using Data from the 1987 Whittier Narrows Earthquake

Whittier Narrows地震为评估1971年圣费尔南多地震对生命线抗震设计和性能的影响提供了一个机会。圣费尔南多地震是这些系统抗震设计的一个重要转折点，洛杉矶有机会从这一领域的研究中受益。因此，收集惠蒂尔海峡地震的响应和恢复数据不仅可以保存重要但易腐烂的数据，而且可以评估研究的应用和有效性。本研究的目的是：(1)收集、审查和记录1987年10月1日惠蒂尔海峡地震的生命线系统性能（即响应和恢复）数据；(2)利用Whittier Narrows地震和1971年San Fernando地震的数据建立不同生命线系统的初步响应和恢复模型；(3)评估1971年圣费尔南多地震后在生命线区域进行的研究对改进生命线的抗震设计和应急响应和准备程序的影响。将执行的具体任务包括：(1)数据收集和审查；(2)采访生命线人员；(3)建立初步响应和恢复模型；(4) 1971年San Fernando地震与1987年Whittier Narrows地震的生命线响应与恢复性能比较；(5) 1971年圣费尔南多地震后进行的研究对生命线抗震设计和性能的影响评价。

The Whittier Narrows earthquake offers an opportunity to assess the impact that research conducted as a result of the 1971 San Fernando earthquake has had on the earthquake design and performance of lifelines. The San Fernando earthquake was a major turning point in the seismic design of these systems, and Los Angeles has had the opportunity to benefit from research conducted in this area. Therefore, collecting response and recovery data from the Whittier Narrows earthquake would not only allow the preservation of important but perishable data, but also an assessment of research application and effectiveness. The objectives of this proposed study are to (1) collect, review, and document lifeline system performance (i.e., response and recovery) data from the October 1, 1987 Whittier Narrows earthquake; (2) develop preliminary response and recovery models for different lifeline systems using data from the Whittier Narrows earthquake and the 1971 San Fernando earthquake; and (3) assess the impact that research in the lifelines area conducted after the 1971 San Fernando earthquake has had on the improvement of seismic design and emergency response and preparedness procedures for lifelines. Specific tasks that will be performed include (1) data collection and review; (2) interviews with lifeline personnel; (3) development of preliminary response and recovery models; (4) comparison of lifeline response and recovery performance during 1971 San Fernando earthquake and 1987 Whittier Narrows earthquake; and (5) assessment of impact of research conducted after 1971 San Fernando earthquake on seismic design and performance of lifelines.
