The tube structural system was developed for improving the resistance to lateral forces (wind or earthquake) and the control of drift (lateral building movement) in highrise building. The stressedskin tube takes the tube system a step further. The development of the stressedskin tube utilizes the facade of the building as a structural element which acts 5 with the framed tube, thus providing an efficient way of resisting lateral loads in highrise buildings, and resulting in costeffective columnfree interior space with a high ratio of to gross floor area. Because of the contribution of the stressedskin facade, the framed members of the tube require less mass, and are thus lighter and less expensive. All the typical columns and spandrel beams are standard rolled shapes, minimizing the use and cost of special builtup members. The depth requirement for the perimeter spandrel beams is also reduced, and the need for upset beams above floors, which would encroach on valuable space, is minimized. The structural system has been used on the 54story One Mellon Bank Center in Pittsburgh. Systems in concrete. While tall buildings constructed of steel had an early start, development of tall buildings of reinforced concrete progressed at a fast enough rate to provide a petitive challenge to structural steel systems for both office and apartment buildings. Framed tube. As discussed above, the first framed tube concept for tall buildings was used for the 43story DeWitt Chestnut Apartment Building. In this building, exterior columns were spaced at () centers, and interior columns were used as needed to support the (20cm) flatplate concrete slabs. Tube in
