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8时05分，哥伦比亚波哥大发生一起汽车炸弹袭击，造成33人死亡，155人受伤，袭击的对象是最近建造的现代多层建筑El Nogal大楼。钢筋混凝土结构体系遭到广泛破坏。需要资金来进行一项为期12个月的工作，重点是收集与这一事件相关的数据，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，美国建筑规范要求的常规地震细节是否会导致结构在汽车炸弹和类似装置的爆炸荷载下具有足够的性能。El Nogal的经验非常适合于测试这一概念，因为该结构是根据哥伦比亚建筑规范详细说明的，该规范与美国使用的建筑规范非常相似。波哥大的El Nogal大楼的设计考虑了与美国地震设计2类建筑相同的地震考虑。这次活动提供了一个独特的机会来检验这一前提。据信，所观察到的损害控制是由于在设计和施工中使用了“地震细节”。明确确认这一信念将有助于改善美国和美国在世界其他地区拥有的建筑物的安全。El Nogal建筑结构工程师路易斯·加西亚教授目前是普渡大学的研究人员。此外，建筑物所有人已决定重建，并聘请加西亚先生陪同进行损失评估，并就与重建进程有关的结构方面开展工作。因此，保证了方便地进入结构的所有方面，包括进入结构图纸和原始结构的设计过程，进入损害评估作业，最后进入重建工作。请拨26719美元，用于开展为期12个月的工作，重点是收集与这一活动有关的数据，并对这些数据进行初步评价。这笔款项将用于支付与数据收集和初步分析任务有关的人员和旅费。
