Damage to Public Property from the Loma Prieta Earthquake: Analysis and Comparison to Whittier Experience and ATC Estimates

该项目涉及对洛马、普里塔和惠蒂埃地震对公共财产造成的损害进行比较分析。研究的具体目标是：(1)收集对公共设施，包括公共建筑物、街道、桥梁和下水道系统以及每类损坏的文件修复和更换费用；(2)编制单向描述性统计数据，显示总体损害模式和每个司法管辖区的损害模式；(3)将各类设施的损毁分布与惠蒂尔纳罗斯地震的损毁分布进行比较，并检验以下假设各级别损害赔偿比例相同；(4)根据每个案件研究辖区内的实际损失和财产金额和价值的次要数据，计算各系统的损害率；以及(5)将惠蒂尔纳罗斯地震和洛马普里塔地震的实际损失与实际损失进行比较用ATC-13损伤估计法进行预测，并确定各损伤值与预测值的变化。

This project involves a comparative analysis of damage to public property caused by the Loma Prieta and Whittier earthquakes. Specific objectives of the study are: (1) to collect a detailed listing of physical damage to public facilities including public buildings, streets, bridges and water sewer systems and document repair and replacement costs for each class of damage; (2) to produce one way descriptive statistics that show the overall damage pattern and the damage pattern for each jurisdiction; (3) to compare the distribution of damage across types of facilities with that experienced in the Whittier Narrows earthquake and test the hypothesis that the proportion of damages for each class is the same; (4) to calculate damage ratios for various systems based on the actual losses and secondary data on the amount and value of property in each case study jurisdiction; and (5) to compare the actual damage experienced in both Whittier Narrows and the Loma Prieta earthquakes to the damage predicted by the ATC-13 damage estimation method and determine the variation of each to the predicted values.
