This project will support a reconnaissance team using recently developed handheld technology to collect damage assessment data from structures damaged during the terrorist attack on the World Trace Center. The team will use the PQuake system developed by the Principal Investigator under NSF support for collection of damage data immediately after earthquakes. The system includes a GPS for recording location, a digital camera for photographic records, a handheld computer with customized software for recording data and a digital voice recorder to rapidly record notes. This system has been used successfully following the earthquake in Gujarat, India. Only minor modifications would be required in the software to adapt it for use in collecting damage from terrorist attacks, as the system already designed to record structural damage.The purpose of the data collection is threefold. First, systematic collection of damage data from structures damaged, but not destroyed, during the terrorist attack will aid in the assessment of the structural integrity of these buildings. These data will speed up the assessment of damage and the repair of these structures. Second, the data will serve as a valuable resource for future research related to performance of structures subjected to terrorist attack, explosions and fires; the development of methods of minimizing damage from such occurrences; and future design of urban structures. Third, this work will support the development of data acquisition and storage protocols for all post-disaster reconnaissance activities. The earthquake engineering community in particular is just starting to address the question of how to collect and archive data. The PI is a pioneer in the utilization of handheld technology for rapid data collection. This project will provide continued support for the development of these methods and will extend their use to disasters other than earthquakes.

该项目将支持一个侦察小组使用最近开发的手持技术，从世界追踪中心恐怖袭击中受损的结构中收集损害评估数据。该小组将使用由首席研究员在美国国家科学基金会的支持下开发的PQuake系统，用于在地震后立即收集损害数据。该系统包括用于记录位置的GPS、用于摄影记录的数码相机、用于记录数据的带有定制软件的掌上电脑和用于快速记录笔记的数字录音机。该系统在印度古吉拉特邦地震后得到了成功应用。只需要对软件进行微小的修改，使其适应于收集恐怖袭击造成的损害，因为该系统已经设计用于记录结构损坏。数据收集的目的有三个。首先，系统地收集在恐怖袭击中受损但未被摧毁的建筑物的损坏数据，将有助于评估这些建筑物的结构完整性。这些数据将加快对损坏情况的评估和对这些结构的修复。其次，这些数据将成为未来研究遭受恐怖袭击、爆炸和火灾的结构性能的宝贵资源；制定尽量减少此类事件造成的损害的方法；以及未来城市结构的设计。第三，这项工作将支持为所有灾后侦察活动开发数据采集和存储协议。特别是地震工程界刚刚开始解决如何收集和存档数据的问题。PI是利用手持技术进行快速数据收集的先驱。该项目将继续支持这些方法的发展，并将其应用于地震以外的灾害。
