Structural Developments in Tall Buildings: Current Trends and Future Prospects

Abstract: Tall building developments have been rapidly increasing worldwide. Tis paper reviews the evolution of tall building’s structural systems and the technological driving force behind tall building developments. For the primary structural systems, a new classification – interior structures and exterior structures – is presented. While most representative structural systems for tall buildings are discussed, the emphasis in this review paper is on current trends such as outrigger systems and diagrid structures. Auxiliary damping systems controlling building motion are also discussed. Further, contemporary “out-of-the-box” architectural design trends, such as aerodynamic and twisted forms, which directly or indirectly affect the structural performance of tall buildings, are reviewed. Finally, the future of structural developments in tall buildings is envisioned briefly.
Keywords: Aerodynamics, Building forms, Damping systems, Diagrid structures, Exterior structures, Interior structures, Outrigger systems, Structural performance, Structural systems, Tall buildings

The Western Association of State Highway and Transportation Officials (WASHTO) has recognized this problem and has set forth a process to bring vehicle uniformity to the West and to attack unnecessary regulatory roadblocks that stand in the way of increased productivity. In 1987 WASHTO Chief Administrative Officers adopted a resolution committing development of uniformity in truck size and weight as the top priority of its’ Subcommittee on Highway Transport, (which became the Committee on Highway Transport in 1995).
This resolution set in motion a rather unique effort to attack the problem. Every state and federal department belonging to WASHTO assigned representatives to the Subcommittee. This insured that not only every state had equal and ample opportunity of involvement, but it produced a group of wide spread experts ranging from top level to first line state representatives who work daily with the laws and regulations governing large vehicles. Early commitment was made by the Subcommittee to heavily involve the private sector in the process. As a result, the Western Trucking Association Executive Council, the Western Highway Institute and the Specialized Carriers and Riggers Association joined the efforts.

Steel-framed structures in high-rise office buildings have historically survived fire exposures extremely well. Two examples of severe fires are the 1988 First Interstate Bank fire in Los Angeles and the 1991 One Meridian Plaza fire in Philadelphia; the details of these and other significant building fires are given in Section 7.2. In fact, there has been no recorded structural failure of a protected high-rise steel frame building solely due to fire.

Facts for Steel Buildings #3: Earthquakes and Seismic Design
71 pages
17.8mb
Why was destruction so widespread in Haiti and would a similar earthquake be as devastating in the U.S.? A new publication from the American Institute of Steel Construction, the group that writes the specification for the seismic design of steel buildings in the U.S., provides a broad understanding of earthquakes and how they affect buildings. While Facts for Steel Buildings Number 3: Earthquakes and Seismic Design was written prior to and does not directly address the situation in Haiti, the reader gains a basic understanding of earthquake engineering and the U.S. buildings codes that are designed to prevent this level of catastrophe.
Written by Ronald O. Hamburger of Simpson Gumpertz & Heger, Inc., this publication presents an overview of the causes of earthquakes, the earthquake effects that damage structures, the structural properties that are effective in minimizing damage, and the organization and intent of seismic design requirements for steel structures in the U.S. today and also looks at the future of seismic design. Hamburger is one of the world’s leading experts on seismic design and chairs the AISC committee responsible for prequalifying moment connections for use in high-seismic applications. He’s a past president of the National Council of Structural Engineers Associations and played a key leadership role in the post-Northridge earthquake research that helped to create our current seismic design standards. For his work on performance-based seismic design, he received the AISC T.R. Higgins Lectureship Award in 2007.
