Proposal for a Workshop to Design a Soil-Structure Interaction Experiment

人们认识到，在强震作用下，土-结构相互作用会改变结构体系的反应特性。然而，目前还没有测量建筑物的强震数据来证实土-结构相互作用分析方法和程序的有效性，尽管这种相互作用的影响现已包括在各种地震规范(如ATC-3、NEHRP-1985)中。1978年至今举办的讲习班多次包括为研究土壤-结构相互作用而对建筑物进行仪器测量的建议。虽然美国有100多个结构用仪器测量强烈地震地面震动的影响，但没有仪器结构可以详细校准和/或确认土-结构相互作用分析方法的有效性。这次研讨会的目标是计划和设计这样一个实验，该实验由美国地质调查局进行。这一行动是为了支持国家科学基金会的这一倡议。这次研讨会的目的是：(A)召集一个专家小组，就通过在美国地震活跃地区的建筑中安装仪器来实施土-结构相互作用实验的好处和可行性达成共识，以及(B)计划此类实验的细节。

It is recognized that soil-structure interaction during strong earthquake ground shaking alters the response characteristics of a structural system. However there are no strong-motion data from instrumented buildings to confirm the validity of the soil-structure interaction analysis methods and procedures; even though the effects of this interaction are now included in various seismic codes (e.g. ATC-3, NEHRP-1985). Workshops held between 1978 and the present have repeatedly included the recommendation to instrument a building for soil-structure interaction studies. Although there are over 100 structures in the U.S. instrumented to measure the effects of strong earthquake ground shaking, there are no instrumented structures that would allow detailed calibration and/or confirmation of the validity of soil-structure interaction analysis methods. The objective of this workshop is to plan for and to design such an experiment, which is being undertaken by the U.S. Geological Survey. This action is for support of this initiative by the National Science Foundation. The purposes of this workshop are: (a) to bring together a panel of experts to reach a consensus on the benefits and feasibility of implementing a soil-structure interaction experiment by instrumenting a building in a seismically-active region of the U.S., and (b) to plan the details for such an experiment.
