Book Description
Proceedings of a session at the ASCE Convention, held in Seattle, Washington, April 8, 1986. Sponsored by the Aerodynamics Committee of the Aerospace Division and the Wind Effects Committee of the Structural Division of ASCE. This collection contains six papers examining the motions of buildings produced by wind. The trend towards higher structural efficiency and lower cost has resulted in a generation of lighter and more flexible buildings with a lower inherent capacity for energy dissipation or damping. Unfortunately, this trend has produced structures that are more sensitive to the dynamic action of wind. The emphasis in the design of modern tall buildings has therefore shifted to requirements that control building movements or drift and that limit wind-induced accelerations. Two papers deal with the action of wind on two important tall buildings where designers relied on wind tunnel model tests for information on wind-induced loads and building motions. The design of the Columbia Seafirst Center took advantage of economies possible as a result of wind tunnel studies., and viscoelastic dampers were added to limit the building's motion and wind-induced acceleration. The recorded response of the Allied Bank Plaza during Hurricane Alicia is an extremely important contribution to the understanding of the action of wind on tall buildings; this is the only existing record of the response of a major building under the action of design winds. Another paper discusses a survey of structural damping found in tall buildings, presenting typical damping values for steel and concrete buildings and discussing the variability of such estimates and its implication on design. The final papers consider damping systems that can be added to tall buildings in order to limit their motion. The use of tuned mass dampers and viscoelastic damping units is discussed and examples are presented to show their practical effectiveness. The viscoelastic dampers used in the Columbia Seafirst Center are described.

Book Description
tenant is looming in importance. The owner is having more influence on the building. As Gerald D. Hines has said, there are indications that the desire for more discretionary time will lead to more residential high-rises dose to or in the midst of downtown office buildings. Downtown living could become the desired alternative. Tall buildings will be approached increasingly from the standpoint of an urban ecology - that what happens to apart can influence the whole. Provid ing for public as well as private needs in a tall building project is just one example (facilities for schools, shops, religious, and other needs). More attention will be paid to maintaining streets as lively and interesting places. Will a new "world's tallest" be built? Will we go a mile high? The answer is probably "yes" to the first, "no" to the second. With the recent spate of super-tall buildings on the drawing boards, going to greater heights was in the back of many people's minds at the Chicago conference. But in the U nited States, at least, buildings of 70 to 80 stories would appear to provide needed space consistent with economy. The future, then, is described in depth by papers that go into specific areas.
