Dr Khan was probably the greatest architectural engineer of the 2nd half of the 20th century. He revolutionized the design and construction of tall buildings through his invention of the "braced tubular system," which allowed the construction of such buildings as the 100-story John Hancock Center and the 110-story Sears Tower in Chicago. He also engineered the roof system for the Haj Terminal in Jeddah, Saudi Arabia, which is the largest roof structure in the world.This will be the first book on the life and work of Fazlur Khan and as such will provide a link to his advancement and technological innovations for future generations of engineers, architects, builders, planners, and administrators in the building field.The book is comprehensive in its treatment of Khan's life and works; it is more than just a biography and will be of interest to architects, engineers, professors, students, and general readers. But most importantly, it will be a key source book for research in the design and construction of tall buildings.
