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.

这是一个事后调查项目，旨在从1989年10月洛马普列塔地震中吸取工程教训。该项目由德克萨斯大学（UT）和H. J. Degenkolb Associates （HJD）合作进行，目的是研究工业建筑在Loma Prieta地震期间的性能及其内容。重点将放在高科技产业的设施上。收集到的数据将用于检查与提供安全和寿命相关的结构设计标准。在设计或改造结构时，应定量地确定维护操作的要求。调查将涉及三项主要工作：(1)对受损建筑物/内容进行实地研究，以及为恢复运作所做的工作，包括（HJD和UT）提供的成本数据；(2)收集选定现有结构的详细资料，以确定问题所在，并评估对该结构（HJD和UT）提出的重新设计的实际使用情况；(3)选定结构的重新设计；对现有的和重新设计的结构进行详细的分析，使用基于可用的测试数据的模型来加强或修复结构元件（由UT）。预计该项目将获得数据，确定改造标准的可行性，提高对关键行业脆弱性的理解，并确定运营维护和事件后快速恢复的长期实验和分析研究需求。
