This Small Grant for Exploratory Research (SGER) project will send an investigation team to the site of the bridge carrying Interstate Highway 35W (I-35W) over the Mississippi River in Minneapolis, Minnesota which collapsed on Wednesday, August 1, 2007, in the main span within a matter of seconds while carrying rush hour traffic. The collapse of a highway bridge in a major downtown area is expected to have tremendous consequences to our society. The tasks are to collect photographic data and to procure perishable material.The results from the project will provide engineers with valuable data to conduct more detailed studies in the coming years. This SGER project is a crucial step towards identifying the causes of the I-35W Bridge collapse, and to assure the society that measures will be taken to substantially reduce the risk that such a tragedy will be repeated. The project addresses a major and immediate problem that the U.S. society currently faces. This project is an important step for researchers in the Civil Engineering field to reassess the safety and reliability of bridges in the U.S. and to thereby regain the trust of society. Considering the important role that bridges play in the economy and daily life of the national population, and considering the substantial public distress caused by the tragedy, the objectives of the research are crucial to the well-being of our society. The PIs will make their best effort to convey the findings from this research widely to the engineering community, and to integrate the findings to educate the next generation of engineers.

这项探索性研究小额赠款 (SGER) 项目将派遣一个调查小组前往明尼苏达州明尼阿波利斯市密西西比河上 35W 州际公路 (I-35W) 的桥梁现场，该桥梁于 2007 年 8 月 1 日星期三在交通高峰时段在主桥上几秒钟内倒塌。主要市中心地区公路桥梁的倒塌预计将对我们的社会产生巨大影响。任务是收集摄影数据并采购易腐烂的材料。该项目的结果将为工程师提供有价值的数据，以便在未来几年进行更详细的研究。 SGER 项目是确定 I-35W 大桥倒塌原因的关键一步，并向社会保证将采取措施大幅降低此类悲剧重演的风险。该项目解决了美国社会当前面临的一个重大而紧迫的问题。该项目是土木工程领域的研究人员重新评估美国桥梁的安全性和可靠性，从而重新获得社会信任的重要一步。考虑到桥梁在国民经济和日常生活中发挥的重要作用，并考虑到悲剧造成的巨大公众痛苦，研究的目标对于我们社会的福祉至关重要。 PI 将尽最大努力将这项研究的结果广泛传达给工程界，并整合这些研究结果来教育下一代工程师。
