UJNR Soil-Structure Interaction Workshop

9807562塞莱比在工程结构的设计/分析过程中，一直假定结构的基础固定在刚性的下层介质上。然而，在过去的四十年里，人们已经认识到土-结构相互作用改变了结构体系的响应特性。在重要的工程结构中，采用详细的数值方法和闭合形式解方法来进行土-结构分析。到目前为止，测量建筑物的地震强震数据不足以证实土-结构相互作用分析方法和程序适用于核电站以外的结构的有效性。1997年5月在日本筑波举行的美国-日本自然资源开发计划(UJNR)的风和地震影响小组会议期间，决定举办一次关于土壤-结构相互作用的研讨会。这一行动的目的是为本组织将于1998年9月在加利福尼亚州门洛帕克举行的UJNR研讨会提供部分支持。研讨会将汇集日本和美国这一领域的专家，讨论各种专题，包括：(A)日本和美国在设计/分析过程中使用的当前SSI方法，(B)最近正在进行的研究，(C)正在开发和正在开发的试验性SSI研究阵列和/或设施，以及(D)寻找在未来SSI研究方面进行合作的方法。研讨会的好处将是交流关于SSI的详细信息和数据，并为日本和美国研究人员之间发展新的合作研究提供途径。

9807562 CELEBI During the design/analysis process for engineered structures, it has been assumed that the foundation of a structure is fixed to a rigid underlying medium. In the last four decades, however, it has been recognized that soil-structure interaction alters the response characteristics of a structural system. In important engineered structures, detailed numerical and closed-form-solution methods are applied to perform soil- structure analyses. To date, the earthquake strong-motion data from instrumented buildings are insufficient to confirm the validity of the soil- structure interaction analysis methods and procedures as applied to structures other than nuclear power plants. During the May 1997 meeting of the Panel on Wind and Seismic Effects of the United States Japan Natural Resources Development Program (UJNR) held in Tsukuba, Japan, it was decided to hold a workshop on Soil- Structure Interaction (SSI). The purpose of this action is to provide partial support for the organization this UJNR workshop, to be held in Menlo Park, California, September 1998. The workshop will bring together experts in the field from Japan and the United States to discuss various topics, including: (a) current methods of SSI used in design/analyses processes in both Japan and the United States, (b) recent researches that are being carried out, (c) experimental SSI research arrays and/or facilities developed and that are in the process of being developed and (d) searching for ways to cooperate on future SSI research. The benefits of the workshop will be to exchange detailed information and data on SSI and to provide avenues for the development of new cooperative research between Japanese and US researchers.
