Analysis of the Seismic Response of the Jualien Containment Model

9528057 Luco本项目使用台湾花莲核安全壳结构1/4比例模型中记录的大量地震响应数据来验证一组数学模型和计算机代码。这些数学模型和计算机程序被用来计算当结构与周围土之间的相互作用的影响是显着的重要结构的地震反应。 花莲实验由美国电力研究院（EPRI）和核管理委员会（NRC）以及台湾、日本、韩国和法国的机构等组织组成的联盟进行。该项目的第一项任务是根据远离结构的自由场地面上记录的地面运动预测安全壳模型的地震响应。在第二项任务中，预测与观测结果进行比较，以获得对当前能力的总体评估，以模拟部分嵌入土壤中的结构的地震响应，当土-结构相互作用效应很重要时。最后，识别技术用于从记录的数据中推断结构和土壤的一些特征。 ***

9528057 Luco This project uses the extensive seismic response data recorded within the Hualien, Taiwan, 1/4-scale model of a nuclear containment structure to validate a set of mathematical models and computer codes. These mathematical models and computer codes are used to calculate the seismic response of important structures when the effects of the interaction between the structure and the surrounding soil are significant. The Hualien experiment is being conducted by a consortium of organizations including the Electric Power Research Institute (EPRI) and the Nuclear Regulatory Commission (NRC) in the U.S. and institutions from Taiwan, Japan, Korea and France. The first task of the project is to predict the seismic response of the containment model on the basis of ground motions recorded on the free-field ground surface away from the structure. In a second task, the predictions are compared with the observations to obtain an overall assessment of the current capability to model the seismic response of structures partially embedded in soils, when soil-structure interaction effects are important. Finally, identification techniques are used to infer from the recorded data some of the characteristics of the structure and the soil. ***
