Can Buildings Be Designed to Resist Terrorist Attack?
In the aftermath of the terrorist attack on the World Trade Center,structural engineers are trying hard to
solve a question that a month ago would have been completely unthinkable:Can buildings be designed to
withstand catastrophic blasts inflicted by terrorists?
Ten days after the terrorist attacks on the twin towers,structural engineers from the University at Buffalo
and the Multidisciplinary Center for Earthquake Engineering Research(MCEER)headquartered at UB
traveled to ground zero as part of a project funded by the National Science Foundation.Visiting the site as
part of an MCEER reconnaissance visit,they spent two days beginning the task of formulating ideas about
how to design such structures arid to search for clues on how to do so in buildings that were damaged but still
are standing.
"Our objective in visiting ground zero was to go and look at the buildings surrounding the World Trade
Center,those buildings that are still standing,but that sustained damage,"said M.Bruneau,Ph.D."Our im-
mediate hope is that we can develop a better understanding as to why those buildings remain standing,while
our long-term goal is to see whether earthquake engineering technologies can be married to existing technolo-
gies to achieve enhanced performance of buildings in the event of terrorist attacks,"he added.
Photographs taken by the investigators demonstrate in startling detail the monumental damage inflicteed
on the World Trade Center towers and buildings in the vicinity.One building a block away from the towers
remains standing,but was badly damaged."This building is many meters away from the World Trade Center
and yet we see a column there that used to be part of that building,"explained A.Whittaker,Ph.D."The
column became a missile that shot across the road,through the window arid through the floor."
The visit to the area also revealed some surprises,according to the engineers.For example,the floor
framing system in one of the adjacent buildings was quite rugged,allowing floors that were pierced by tons of
falling debris to remain intact. " Highly redundant ductile(有延展性的)framing systems may provide a sim-
pie,but robust strategy for blast resistance,"he added.Other strategies may include providing alternate paths
for gravity loads in the event that a load一bearing column fails."We also need a better understanding of the
mechanism of collapse,"said A.Whittaker."We need to find out what causes a building to collapse and how
you can predict it."
A.Reinhorn,Ph.D.noted that"Earthquake shaking has led to the collapse of many buildings in the
past.It induces dynamic response and extremely high stresses and deformations in structural components.So-
lutions developed for earthquake-resistant design may be directly applicable to blast engineering and
terrorist-resistant design.Part of our mission now at UB is to transfer these solutions and to develop new ones
where none exist at present."
选项
The question raised in the first paragraph is one_______.A:that was asked by structural engineers a month agoB:that is too difficult for structural engineers to answer even nowC:that was never imagined before the terrorist attackD:that terrorists are eager to find a solution to
答案
C
解析
建筑设计是否能使建筑具有抵御恐怖袭击的性能,是一个月前世界贸易中心受到袭击 之前人们从未想过的一个问题。这是第一段的主要内容。所以,只有C是正确答案。 A不是正确选项,因为文章没有提及谁首先提出这个项目。B和C都不是文章所述的 内容。答案可以在第三段中找到。 有关本题的句子是第四段的第三句," This building is many meters away from the World Trade Center and yet we see a column there that used to be part of that building.”这里的there指 this building,而this building指的是the building a block away from the World Trade Center towers, 而that building指的是World Trade Center。 选项A不是答案,因为文章说“the floor framing system in one of the adjacent buildings...remain intact." C不是文章表达的内容。D在文中提到,但不是a surprising discovery。只有B 是正确答案。 选项A的内容是正确的,根据是本段最后一句("...develop new ones")。选项B和C 的内容也是正确的,根据是本段最后两句(关键词是applicable和transfer)。只有D是正确答 案。因为Reinhorn没有说blast engineering emerges as a new branch of Science。
