A Study of Damage to Existing Industrial Facilities

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。该项目是由德克萨斯大学(UT)和德根科尔布协会(HJD)共同开展的，目的是研究洛马普里塔地震期间工业建筑的性能及其内容。重点将放在高科技产业的设施上。收集的数据将用于检查与提供安全和生命相关的结构设计标准。将对在设计或改装结构时应对维持业务提出的要求进行量化界定。调查将涉及三项主要任务：(1)实地研究受损建筑物/内容和为恢复运营所做的工作，包括(HJD和UT)的成本数据，(2)收集选定的现有结构的详细信息，以确定问题区域，并评估实际使用的重新设计(HJD和UT)和(3)对于选定的结构，使用基于加固或修复的结构构件(UT)的现有试验数据的模型，对现有和重新设计的结构进行详细分析。预计该项目将获得数据，确定按照标准进行改造的可行性，增进对关键行业脆弱性的了解，并确定长期的实验和分析研究需求，以维持运作和快速灾后恢复。

This is a post-event investigation project to learn engineering lessons from the Loma Prieta earthquake (October 1989). The objective of this project, conducted in companion between the University of Texas (UT) and the H. J. Degenkolb Associates (HJD) is to study the performance of industrial buildings and their contents during the Loma Prieta earthquake. The primary focus will be on facilities in high- tech industries. The data gathered will be used to examine structural design criterial associated with providing safety and life. The requirements that should be given to maintenance of operations when designing or retrofitting a structure will be defined quantitavely. The investigation will involve three major tasks: (1) A field study of damaged buildings/contents and the work done to restore operations, including cost data by (HJD and UT), (2) Gather details of selected existing structures to determine problem areas and to evaluate the redesigns actually used those proposed for the structure (HJD and UT) and (3) for selected structures, conduct detailed analyses of the existing and redesigned structures using models based on available test data for strengthened or repaired structural elements (by UT). It is anticipated that the project will make access to data, determine feasibility of retrofitting to standards, result in improved understanding of vulnerability of critical industries, and identify long-term experimental and analytical research needs for operation maintaining and rapid post-event recovery.
