Soil-Pile Foundation-Structure Response Analysis Using Data from the Loma Prieta Earthquake

本项目旨在总结1989年10月17日北加州（洛马普里塔）地震的经验教训。目的是评估地震中分析土-桩-基础-结构相互作用的最新分析技术，以提高对这一现象的理解，并验证和校准现有技术。这是通过分析加利福尼亚州埃默里维尔一座30层建筑的反应来实现的，使用各种技术来分析地震荷载下的土-桩-结构相互作用。该建筑是一个延性抗弯矩空间框架和墙体结构，由5英尺厚的混凝土垫和900个14英寸乘14英寸的混凝土桩支撑。它配备了强震记录仪器，成功地记录了洛马·普里塔地震期间的建筑运动（USGS Rep.89-568, 1989）：建筑物附近的地面运动也被记录了下来。这项调查涉及与美国地质调查局（USGS）的合作。

This project addresses the lessons learned from the 17 October 1989 Northern California (Loma Prieta) Earthquake. The objective is to evaluate the state-of- the-art analytical techniques for analyzing soil-pile foundation-structure interaction during earthquake shaking, in order to improve the understanding of this phenomenon, and to verify and calibrate existing techniques. This is achieved by analyzing the response of a 30 story building in Emeryville, California, using various techniques for analyzing soil-pile-structure interaction under seismic loading. The building is a ductile moment resisting space frame and wall structure supported by a 5 foot thick concrete mat with 900 14 by 14 inch concrete piles. It is instrumented with strong motion recording instruments which successfully recorded the building motions during the Loma Prieta earthquake (USGS Rep.89-568, 1989): the ground motions adjacent to the building were also recorded. This investigation involves a collaboration with the United States Geological Survey (USGS).
