Earthquake Stability Problems in Eastern North America

人们普遍认为，在未来30年内，美国某地发生特大地震的可能性超过50%。北美东部的脆弱性尤其令人关切。由于东部很少有为地震而设计的建筑，而且东部的高层建筑比西部多，这个问题非常紧迫。结构稳定性研究理事会的这个项目是通过举行一次技术会议来研究北美东部的地震稳定性问题。1992年4月7日至8日在匹兹堡举行的会议，通过一套程序向公众研究领域传播研究成果，并通过对研究研究和设计方法的最终建议。技术会议将包括介绍目前与稳定有关的研究项目的报告。一个特别的专题是主题会议和小组讨论，主题是“北美东部的地震稳定性问题”。在主题会议期间，受邀研究人员将介绍他们最近的调查结果。小组讨论涉及一组工程师，他们将讨论与考虑地震稳定性问题有关的问题设计实践。将讨论最先进的设计规范和设计规范未具体解决的问题。该技术方案将集中于P-Delta效应、动力效应、连接、壳体和管子、平板结构和电气传动等主题。该项目的完成将是确定和解决北美东部问题的重要一步地震稳定性问题。

It is generally agreed that there is a better than 50% chance that a very severe earthquake will strike somewhere in the United States within the next thirty years. The vulnerability of the eastern portion of North America is of particular concern. Since very few structures in the East have been designed for earthquakes, and there are more tall buildings in the East than in the West, the subject is very urgent. This project by the Structural Stability Research Council is to examine earthquake stability problems in Eastern North America through the holding of a Technical Session in Pittsburgh 7-8 April 1992, the dissemination of findings through a set of Proceedings to the public research domain, and through eventual recommendations for research studies and design approaches. The Technical Session will include the presentation of reports on current stability-related research projects. A special feature will be the Theme Session and Panel Discussion which will address the topic of "Earthquake Stability Problems in Eastern North America." During the Theme Session, invited researchers will present the results of their recent investigations. The Panel Discussion involves a group of engineers who will discuss issues related to consideration of earthquake stability problems in design practice. State-of-the-art design specifications and issues not specifically addressed by design specifications will be discussed. The technical program will focus on the topics of P-delta effect, dynamic effects, connections, shells and tubes, plate structures and electrical transmission. The completion of this project shall constitute a significant step toward the identification and resolution of Eastern North America earthquake stability problems.
