2、nth ago would have been completely unthinkable:Canbuilding be designed to withstand catastrophic blasts inflicted by terrorists?Ten days after the terrorist attacks on the twin towers,structural engineers from the Universityat Buffalo and the Multidisciplinary Center for Earthquake Engineering Resea

3、rch (MCEER)headquartered at UB traveled to ground zer02 as part of a project funded by the National ScienceFoundation. Visiting the site as part of an MCEER reconnaissance visit, they spent two daysbeginning the task of formulating ideas about how to design such structures and searching for clueson

4、how to do so in buildings t at were damaged,but still are standing3.Our objective in visiting ground zero was to go and look at the buildings surrounding theWorld Trade Center,those buildings that are still standing,but that sustained damage4, said M.Bruneau,Ph. D. Our immediate hope is that we can

5、develop a better understanding as to why thosebuildings remain standing, while our long-term goal is to see whether earthquake engineeringtechnologies can be married to existing technologies to achieve enhanced performance of buildings6in the event of terrorist attacks. he added.Photographs taken by

6、 the investigators demonstrate in startling detail the monumental damageinflicted on the World Trade Center towers and buildings in the vicinity. One building a block awayfrom the towers remains standing,but was badly damaged. This building is many meters away.fromthe World Trade Center and yet we s

7、ee 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 thewindow and through the floor. The visit to the area also revealed some surprises,according to the engineers. For example,thefloor framing8 systems in

8、 one of the adjacent buildings was quite rugged,allowing floors that werepierced by tons of falling debris to remain intact9. Highly redundant ductile framing systems mayprovide a simple,but robust strategy for blast resistance. he added. Other strategies may includeproviding alternate paths for gra

9、vity loads in the event .that a load-bearing column fails. We alsoneed a better understanding of the mechanism of collapse , said A. Whittaker. We need to find outwhat causes a building to collapse and how you can predict it. A. Reinhom,Ph. D. noted that earthquake shaking has led to the collapse of

10、 many buildings inthe past. It induces dynamic response and extremely high stresses and deformations in structuralcomponents. Solutions developed for earthquake-resistant design may be directly applicable to blastengineering and terrorist-resistant design. Part of our mission now at UB is to transfe
