Implications of Recorded Data on Earthquake Resistant Design

这是1989年10月洛马普列塔地震后的一个调查项目，旨在从这次破坏性事件中吸取教训。该项目的目标是通过更好地了解地震输入和非弹性结构反应来改进结构的抗震设计。记录建筑物反应的数据库将用于：(1)评估记录的地面运动的潜在破坏；(2)收集建筑物和高速公路结构细节和记录的响应；(3)建立分析模型并进行时程分析；(4)估计潜在破坏；(5)生成非弹性设计响应谱。该研究将对设计延性和抗屈服地震系数的取值提出建议，以供设计实践使用。

This is a post Loma Prieta earthquake (Oct. 1989) investigation project in learning from this damaging event. The goal of this project is to improve the seismic design of structures through a better understanding of seismic input and the inelastic structural response. The database of the recorded building response will be used to: (1) evaluate the damage potential of recorded ground motion, (2) collect building and freeway structure details and recorded response, (3) develop analytical models and perform time-history analysis, (4) estimate damage potential, and (5) generate inelastic design response spectrum. The study will produce recommendations on the values for design ductility and the yield resistant seismic coefficient to be used in design practice.
