Performance of El Nogal Building during the Bomb Attack of 2/7/03

2003年2月7日晚8时05分，哥伦比亚波哥大市发生一起汽车炸弹袭击事件，造成33人死亡，155人受伤，当时炸弹击中了最近建造的现代多层建筑El诺加尔大楼。对钢筋混凝土结构系统的破坏是广泛的。要求提供资金，以开展为期12个月的工作，重点是收集与这一事件有关的数据，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地震细节是否会导致受到汽车炸弹和类似装置爆炸载荷的结构的适当性能。El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El诺加尔大楼在设计时考虑的抗震因素相当于美国抗震设计类别2下的建筑物所需考虑的抗震因素。这次活动提供了一个独特的机会来检验这一前提。据认为，所观察到的破坏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改善美国境内以及美国在世界其他地区拥有的建筑物的安全。El诺加尔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，该建筑物的所有人已决定重建，并聘请Garcia先生的公司进行损坏评估，并处理与重建进程有关的结构问题。因此，保证了对结构的所有方面的方便访问，包括访问结构图纸和原始结构的设计过程，访问损坏评估操作，以及最后，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，重点收集与这一活动有关的数据，并对这些数据进行初步评价。这些资金将用于支付与数据收集和初步分析任务有关的人员和差旅费。

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.
