Preliminary Damage Assessment of the Bingol Earthquake

2003年5月1日凌晨3点27分（当地时间），在Bingol以北10公里处发生矩级6.4级地震（USGS和韩国地震研究所）。震中位于北纬38.94度-东经40.51度（东经erd -安卡拉）。地震深度估计为6公里。这次地震最强烈的记录发生在宾戈尔。该记录的三个分量的峰值地面加速度（PGA）分别为0.55g （NS）、0.28g （EW）和0.47g （UP）。强震持续时间为17秒。地震后，12座建筑物倒塌，13座建筑物严重受损。又据报道，几座桥梁似乎已被摧毁，等待核查。官方公布的死亡人数和受伤人数分别为105人和600人。小组的主要目标是记录：(a)对钢筋混凝土框架建筑和纪念碑的破坏，(b)对桥梁结构的破坏，以及(c)该事件的岩土和地质方面。根据我们在1999年土耳其马尔马拉和杜兹地震余波中的经验，我们知道记录在地面运动中幸存下来的结构的属性与记录受损建筑的属性同样重要。因此，我们打算利用我们在Bingol的时间不仅记录损坏的结构，也记录未损坏的结构。我们还计划使用Bingol的数据来扩展我们的数据库（anatolianquake.org），并测试和改进用于评估地震脆弱性的方法。意义：建议以尽可能精确的形式收集和记录与Bingol事件相关的科学易腐数据，以便与感兴趣的工程师和科学家分享这一经验。希望对这些数据的仔细研究将有助于美国、土耳其和世界其他地震区减轻地震危害的努力。特别是，从4-5层钢筋混凝土结构的性能中可以获得大量的知识。这种结构在美国中西部和东部比比皆是。此外，记录桥梁性能对于帮助规范开发人员和工程师处理美国桥梁的地震升级也很重要。此外，该调查建议与METU的研究人员密切合作，以促进土耳其和美国在地震工程领域的合作活动。为此，我们要求28 202美元，用于支付一个由8名成员组成的小组的旅费和其他有关费用。

The earthquake of moment magnitude 6.4 (USGS and KOERI) occurred at 10 km north of Bingol at 03:27 am (local time) on 1 May 2003. The epicenter of the earthquake was at 38.94N- 40.51E (ERD-Ankara). The depth of the quake was estimated to be at 6 km. The strongest record of the earthquake was recorded at Bingol. The peak ground accelerations (PGA) of the three components of this record are 0.55g (NS), 0.28g (EW) and 0.47g (UP). The duration of the strong motion is 17 s. After the earthquake 12 buildings were collapsed and 13 buildings were damaged severely. It was also reported that several bridges appear to have been destroyed pending verification. The official numbers of fatalities and injuries were 105 and 600, respectively. The main objectives of the group are to document: (a) the damage to reinforced concrete frame buildings and monuments, (b) the damage to bridge structures, and (c) the geotechnical and geological aspects of the event. From our experience in connection with the aftermath of the 1999 Marmara and Duzce earthquakes in Turkey, we know that documenting the properties of the structures that survived the ground motion is as important as documenting the properties of the damaged buildings. Therefore, we intend to use our time in Bingol to document not only the damaged but also the undamaged structures. It is also our plan to use the data from Bingol to expand our database (anatolianquake.org) and to test and improve the methods developed for assessing earthquake vulnerability. Significance: The collection and recording of scientific perishable data related to the Bingol event in as precise form as possible is proposed so that this experience can be shared with interested engineers and scientists. It is hoped that the careful study of the data shall contribute to earthquake hazard mitigation efforts in the US, Turkey and other seismic regions of the world. In particular, there is a great deal of knowledge to be gained from the performance of 4-5 story reinforced concrete structures. Such structures abound in the Midwest and Eastern United States. Also, it is important to document the bridge performance to assist code developers and engineers dealing with seismic upgrading of bridges in the US. Furthermore, the investigation is proposed in close collaboration with researchers from METU, to promote cooperative activities between Turkey and the USA in the field of earthquake engineering. For this effort we are requesting $28,202.00 to cover travel and other related expenses for a team consisting of eight members.
