On the evening of 7 February 2003, at 8:05 PM, in the city of Bogota Colombia a car bomb attack caused 33 deaths and 155 injuries when it impacted the El Nogal Building, a recently constructed, modern multi-story structure. The damage to the reinforced concrete structural system was extensive. Funding is requested to conduct a 12-month effort focused on the collection of data related to this event and to conduct a preliminary evaluation of these data.Since the Murrah Federal Building attack, a central question has been whether routine seismic details required by US building codes would result in adequate performance of structures subjected to blast loading from car bombs and similar devices. The El Nogal experience is ideally suited for testing that concept because the structure was detailed in accordance with the Colombian Building Code, which is very similar to building codes used in the US. The El Nogal Building in Bogota was designed with seismic considerations equivalent to those required in a building under Seismic Design Category 2 in the United States. This event provides a unique opportunity to test this premise. It is believed that the observed containment of damage was due to the use of "seismic details" in the design and construction. To confirm this belief explicitly will aide in improving security of structures in the United States and those owned by the United States in other parts of the world. The El Nogal Building structural engineer of record, Prof. Luis Garcia, is currently on the research staff at Purdue University. Moreover, the owner of the structure has made the decision to rebuild and has retained the company of Mr. Garcia to conduct the damage assessment and to work on the structural aspects related to the rebuilding process. Thus, convenient access to all aspects of the structures is guaranteed, including access to the structural drawings and design process of the original structure, to the damage assessment operation, and finally, to the rebuilding work. Funding in the amount of $26,719 is requested to conduct a 12-month effort focused on the collection of data related to this event and to conduct a preliminary evaluation of these data. The monies would be used to cover personnel and travel expenses related to the tasks of data collection and preliminary analysis.

2003 年 2 月 7 日晚上 8 点 05 分，哥伦比亚波哥大市发生汽车炸弹袭击，袭击了新近建成的现代多层建筑 El Nogal 大楼，造成 33 人死亡、155 人受伤。钢筋混凝土结构系统遭到广泛破坏。需要资金进行为期 12 个月的工作，重点收集与该事件相关的数据，并对这些数据进行初步评估。自默拉联邦大楼袭击以来，一个核心问题是，美国建筑规范所要求的常规抗震细节是否能够使结构在承受汽车炸弹和类似装置的爆炸载荷时具有足够的性能。埃尔诺加尔的经验非常适合测试这一概念，因为该结构是根据哥伦比亚建筑规范详细设计的，这与美国使用的建筑规范非常相似。波哥大的埃尔诺加尔大楼的抗震考虑与美国抗震设计 2 类建筑的抗震考虑相同。这次活动提供了一个独特的机会来检验这一前提。据信，所观察到的损害遏制是由于在设计和施工中使用了“抗震细节”。明确确认这一信念将有助于提高美国境内以及美国在世界其他地区拥有的建筑物的安全性。埃尔·诺加尔大楼 (El Nogal Building) 的记录结构工程师路易斯·加西亚 (Luis Garcia) 教授目前是普渡大学的研究人员。此外，该建筑的业主已决定重建，并聘请加西亚先生的公司进行损害评估并处理与重建过程相关的结构方面的工作。这样，就保证了对结构各个方面的方便访问，包括访问原始结构的结构图纸和设计过程，到损坏评估操作，最后到重建工作。 请求提供 26,719 美元的资金，用于开展为期 12 个月的工作，重点收集与该活动相关的数据并对这些数据进行初步评估。这些资金将用于支付与数据收集和初步分析任务相关的人员和差旅费。
