If he cited the achievements of Americas Muslim citizens in a speech previous this month in Cairo, Egypt, President Barack Obama designated one of the twentieth centurys pre-eminent structural designers, whose heritage lives on for Lehigh twenty seven years after his transferring.
In his addresses, Obama listed Fazlur Rahman Khan, Malcolm Back button, Muhammad Ali and other scientists, politicians and athletes while American Muslims who had made significant advantages to the United states of america.
Khan, who merged executive with appearances while building the Ruben Hancock Middle, the Target Tower and a host of additional innovative constructions, received an honorary doctorate of science degree coming from Lehigh in 1980.
Two years later, when justin was 52, Khan died while traveling in Saudi Arabia. Lehigh, led by the late Lynn Beedle, university distinguished teacher of city engineering, responded with a 20-year effort to raise funds to endow a school chair in Khans name.
In 2006, Dan M. Frangopol, an international expert inside the design, monitoring and life-cycle analysis of structures, became the first Fazlur R. Khan Endowed Chair of Structural Engineering and Architecture in Lehigh.
One of Frangopols first acts next his scheduled appointment at Lehigh was to trigger and coordinate the Fazlur Rahman Khan Lecture Series, which in days gone by two years has had nine in the worlds leading structural technical engineers and are usually to Lehigh.
Born in 1929 in Bangladesh (then part of India), Khan received his bachelors degree from the University of Dhaka and two masters certifications and a Ph. G. from the College or university of Illinois at Urbana-Champaign. He became a member of the Chicago-based international system and engineering firm of Skidmore, Owings and Merrill LLP (SOM), was known as partner in 1966 and remained there until his death. Khan became an U. S. citizen in 1967.
Khan was extensively credited with revolutionizing Chicagos skyline along with his engineering types of the Sears Tower, as soon as the worlds tallest building, as well as the Hancock Centre, which, at 100 tales, is one of the planets highest multi-use buildings.
The Hajj Terminal at Full Abdul Aziz International Airport in Jeddah, Arab saudi, is considered one particular of Khans the majority of impressive patterns. It fits Muslims producing the gross annual pilgrimage to Mecca in giant Teflon-coated tents which can be suspended by high-strength cabling. Openings at the tops with the tents immediate hot wasteland air up and from the tents, therefore cooling the terminal.
Khan also designed the U. H. Air Force Academy in Colorado Springs, the Hubert H. Humphrey Metrodome in Minneapolis, and the Baxter Travenol Laboratories in Deerfield, Unwell., whose roofing is hung from cabling.
Mark Sarkisian, who received an Meters. S. in structural executive from Lehigh in 1985 and is at this point a partner with SOM, offered the premiere Khan Lecture in March 2007.
Sarkisian credited Khan with leading a renaissance in skyscraper construction simply by tuning buildings to the energetic forces of gravity, wind flow and earthquake. Khan attained a mastery of structural anatomist principles, Sarkisian said, at the time of unprecedented flexibility to the architects with whom he worked with.
It was Khan, Sarkisian explained, who confirmed engineers how you can group beam-column frames in to bundles, therefore strengthening a tower, reducing the amount of metallic and concrete floor necessary to support it, and creating open up space in a buildings home. Khan also learned to offset the impact of wind by simply tapering high buildings and fitting associated with strategic indentations. And Khan helped expose the use of large, exposed, diagonal braces, for aesthetic uses as well as structural support.
In other words, Sarkisian said, Khan helped convert the city environment by looking into making it possible for people to live, work and dream in cities above.
Dan M. Frangopol is usually the Fazlur R. Khan Endowed Chair of Structural Architectural and Buildings at Lehigh.
Frangopol, whom came to Lehigh from the University or college of The state of colorado at Boulder, studies cycle engineering, which will optimizes the investment produced in a framework or network of buildings by with the conflicting demands placed on them. It engages probability and statistics to account for the changes structures undertake during their life time.
A framework should be organized and created for a life cycle of 50 to a century, or more, he says. During this time, set ups may be confronted with abnormal tons of different types, starting from natural risks, such as earthquakes, floods, and hurricanes, to man-made unfortunate occurances, such as terrorist attacks, fire, or vehicular collisions. Exact same, structural performance undergoes progressive deterioration because of material the aging process, harsh environmental conditions, and increasing a lot.
From the beginning, you must estimate how much cash you need to dedicate to boost the cost of maintaining and restoring structures above their life time.
Frangopol is a founding manager of Framework and Facilities Engineering, an international peer-reviewed diary dedicated to improvements in repair, management and life-cycle efficiency of a broad variety of structures and infrastructures. He holds two honorary doctorates, has published or co-authored more than 4 hundred refereed publications, and is the editor or co-editor greater than 20 literature.
