Japan Earthquake Reconnaissance in Structural Engineering

1995年1月17日上午，日本中部地区发生强烈地震。目前，地震影响的细节尚不清楚。然而，死亡人数已超过5000人，有证据表明，民用基础设施遭到广泛破坏，包括数千座工程建筑遭到破坏和倒塌。土工和结构问题似乎都是造成已观察到的破坏的原因。虽然日本和美国的情况有很多不同，但很明显，这一悲惨事件为美国的建设实践提供了许多教训。除非尽快努力收集易腐烂的数据，否则许多经验教训将会丧失。该项目通过美国国家科学基金会的SGER奖励机制提供支持，从美国召集一个研究小组前往震中地区，收集数据，准备书面报告，并与美国其他具有类似任务的小组进行协调。该队集中注意下列两个具体领域：(a)建筑结构和(b)桥梁结构将编写和分发一份关于侦察队调查结果的技术报告。

9520108 Moehle On the morning of 17 January 1995, a strong earthquake shook the central portion of Japan. At this time, the details of the effects of the earthquake are unclear. However, the death toll has risen above 5000, and there is evidence of widespread disruption of the civil infrastructure, including damage and collapse of thousands of engineered structures. Both geotechnical and structural issues appear to have contributed to the observed damage. While there are many differences between the conditions in Japan and those in the United States, it is clear that this tragic event holds many lessons for U.S. construction practices. Many of the lessons will be lost unless efforts are made as soon as possible to gather perishable data. This project provides support through NSF's SGER award mechanism to assemble a team of researchers from the United States to travel to the epicentral region, gather data, prepare a written report, and coordinate with other groups from the United States having similar missions. The team focus on the following two specific areas: (a) Building Structures, and (b) Bridge Structures A technical report on the reconnaissance team's findings will be prepared and distributed.
