The Third United States - Japan Natural Resources (UJNR) Workshop on Soil-Structure Interaction

这项行动是为了支持将于2004年初在加利福尼亚举行的第三届美日土壤-结构相互作用研讨会。本次研讨会是在美日自然资源合作项目（UJNR）风与地震影响小组的主持下组织的。UJNR成立于1964年，目的是为了两国的利益，在自然资源领域交换研究信息，以及科学家和工程师。风和地震影响小组成立于1969年。这些研讨会的目的是为两国在该领域的专家提供一个平台，展示他们的工作，交流思想，确定未来的研究需求，并讨论合作。本次研讨会将重点关注土壤-结构相互作用，并将受益于两个重要的发展：美国国家科学基金会乔治·e·布朗地震工程模拟网络（NEES）的启动，以及美国地质调查局（USGS）先进国家地震系统（ANSS）的启动。ANSS将推进国家、区域和城市地震监测以及震后快速信息传递过程的现代化。这两项互补的国家倡议都明确解决了土壤-结构相互作用的问题。土-结构相互作用是结构工程、岩土工程和工程地震学这三个学科交叉的复杂问题。观测结果表明，在强震作用下，土-结构相互作用对结构的性能有显著影响。对这一现象的理解和建模的进步将导致建筑设计实践的改进，更安全的建筑，减少地震造成的生命损失和经济损失。

This action is to support the Third U.S.-Japan Workshop on Soil-Structure Interaction, to be held in California early in 2004. This workshop is organized under the auspices of the U.S.-Japan Cooperative Program in Natural Resources (UJNR) Panel on Wind and Seismic Effects. The UJNR was created in 1964 with the objective of exchanging information on research, as well as scientists and engineers, in the area of natural resources, for the benefit of both countries. The Panel on Wind and Seismic Effects was established in 1969. The purpose of these workshops has been to provide a platform to gather the experts in the field from both countries, to present their work, exchange ideas, identify future research needs, and discuss collaboration.This workshop will focus on soil-structure interaction, and will benefit from two significant developments: The initiation of NSF George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES), and the initiation of the Advanced National Seismic Systems (ANSS) by United States Geological Survey (USGS). The ANSS will advance and modernize the national, regional and urban earthquake monitoring and rapid post-earthquake information delivery process. Both of these complementary national initiatives explicitly address the problem of soil-structure interaction.Soil-structure interaction is a complex problem at the intersection of three disciplines: structural engineering, geotechnical engineering, and engineering seismology. Observations have shown that soil-structure interaction can affect significantly the performance of structures during strong earthquake shaking. Progress in the understanding and modeling of this phenomenon will lead to improvements in building design practices, and to safer construction and the reduction of loss of life and of economic losses from earthquakes.
