Synopsis : Kawasaki Steel Corp. and Shimizu Corp. have developed a unique long span structural system called Super Wing, which utilizes a prestressed steel truss (PSST) and a sliding construction method. During the development of Super Wing, a full-scale 100-meter-span model was tested, and the structural behavior of the PSST was observed both during the prestressing stage and execution of the sliding construction. In addition, the relaxation of prestressing stands was studied experimentally. The wind pressure coefficient of this long span structure was also investigated using a wind tunnel. As a result of these test, Super Wing was proven to be successful as a structural design concept and construction method. |
