Can Buildings Be Designed to Resist Terrorist Attack
In the aftermath of 1 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 building 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 2 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 and searching for clues on how to do so in buildings that were damaged,but still are standing 3.
“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 4," said M. Bruneau,Ph. D. “ Our immediate 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 technologies 5 to achieve enhanced performance of buildings 6 in the event of terrorist attacks. ” he added.
Photographs taken by the investigators demonstrate in startling detail 7 the monumental damage inflicted on the WorldTradeCentertowers 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 and through the floor. ”
The visit to the area also revealed some surprises,according to the engineers. For example,the floor framing 8 systems in one of the adjacent buildings was quite rugged,allowing floors that were pierced by tons of falling debris to remain intact 9. “Highly redundant ductile framing systems may provide a simple, but robust strategy for blast resistance. ” he added. Other strategies may include providing alternate paths for gravity loads in the event that a load-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. Solutions 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. ”

Bold faced, with a hyphen and ending in the adjectival -ed, was coined by Shake speare in Henry VI, Part I, when Lord Talbot, rescuing his son on a French battlefield, spoke of his "proud desire of bold-faced Victorie". It was picked up in the 19th century by typesetters to describe a type-like Clarendon, Antique or a thick version of Bodoni--that stood out confidently, even impudently, from the page. The adjective was used in an 1880 article in The New York Times (we were hyphenated then): "One of the handbills" distributed by the Ku Klux Klan, noted, a disapproving reporter, was "printed in bold-faced type on yellow paper".
Newspaper gossip columnists in the 30’s, to catch the reader’s eye, began using this bold type for the names that made news in what was then called "cafe society" (in contrast to "high" society, whose members claimed to prefer to stay out of those columns).
In our time, the typeface metaphor was applied to a set of famous human faces. A fashion reporter--John Duka of The Times--was an early user of the phrase, as he wrote acerbically on Sept. 22, 1981: "At the overheated parties at Calvin Klein’s apartment, Saks Fifth Avenue, Bergdorf Goodman and Studio 54, the bold-faced names said the week had been so crammed that they were feeling a little under the breath, you know. "
Rita Kempley of The Washington Post noted in 1987 the sought-after status of "a bold-faced name in People magazine"; by 1999, Alan Peppard of The Dallas Morning News recalled to Texas Monthly that he began with a "social column", but "now we live in an age of celebrity, and there are very few people who care about what the debutantes are doing. So I call it celebrity, society, famous people, rich people, bold-faced names".
The New York Times, which never had, does not have and is grimly determined never to have a "gossip column", introduced a "people column" in 2001. (When its current editor, Joyce Wadler, took a six-week break recently, she subheaded that item with a self-mocking "Air Kiss! Smooch! Ciao!") The column covers the doings of celebrities, media biggies, fashion plates, show-biz stars, haut monde notables, perennial personages and others famous for their fame. Its confident, fashionable and modern moniker became the driving force behind the recent popularization of the phrase with the former compound adjective, now an attributive noun: Bold-faced Names.
A:famous human faces. B:famous, rich and celebrated people. C:overheated parties. D:social column.
