Investigation of the Performance of R/C Buildings in the Loma Prieta Earthquake and Evaluation of ATC-14

这是一个事后调查项目，目的是从洛马普里埃塔地震(1989年10月)中吸取工程经验教训。该项目的目标有两个：评估钢筋混凝土建筑物的性能，并通过地震数据分析评估目前的脆弱性评估方法。最具体地说，将对ATC-14号文件进行评价，该文件为快速评估建筑物性能的生命安全水平提供了建议的方法。本次调查的任务是：(A)收集和组织结构性能数据，(B)分析和评估ATC-14格式的结构脆弱性，以及(C)评估ATC-14。该项目将为现场数据的合理验证和结构安全评估方法的改进提供依据。

This is a post-event investigation project to learn engineering lessons from the Loma Prieta earthquake (October 1989). The objective of this project is two-fold: to evaluate the performance of reinforced concrete buildings and to assess, through earthquake data analysis, the current vulnerability evaluation methods. Most specifically the document ATC-14 which provides recommended methodologies for rapid assessment of life-safety level of performance of buildings will be evaluated. The tasks undertaken in this investigation are: (a) collection and organization of structural performance data, (b) analysis and evaluation of structural vulnerability in the ATC-14 format, and (c) evaluation of the ATC-14. The project will provide a rational verification with field data and improvements of structural safety evaluation methodology.
