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

这一行动是为了支持将于2004年初在加利福尼亚州举行的第三届美日土壤-结构相互作用研讨会。这次研讨会是由美日自然资源合作项目(UJNR)风和地震影响小组主办的。UJNR成立于1964年，目的是交流自然资源领域的研究以及科学家和工程师的信息，以造福两国。风和地震影响小组成立于1969年。这些研讨会的目的是提供一个平台，聚集两国该领域的专家，介绍他们的工作，交流想法，确定未来的研究需求，并讨论合作。本次研讨会将侧重于土-结构相互作用，并将受益于两个重要的发展：小乔治·E·布朗国家科学基金会的发起。地震工程模拟网络(NEES)和美国地质调查局(USGS)启动先进的国家地震系统(ANSS)。国家地震监测系统将推进国家、区域和城市地震监测和震后信息快速传递进程，并使之现代化。这两个相辅相成的国家倡议都明确地解决了土-结构相互作用的问题。土-结构相互作用是一个复杂的问题，涉及结构工程、岩土工程和工程地震学三个学科。研究表明，土-结构相互作用对结构在强震作用下的性能有显著影响。在对这一现象的理解和建模方面的进展将导致建筑设计实践的改进，以及更安全的施工和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.
