Book Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thougtit that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 31 (thesis year 1986) a total of 11 ,480 theses titles trom 24 Canadian and 182 United States universities. We are sure that this broader base tor these titles reported will greatly enhance the value ot this important annual reterence work. While Volume 31 reports theses submitted in 1986, on occasion, certain univer sities do re port theses submitted in previousyears but not reported at the time.

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.

Effects of a Tuned Mass Damper on Wind-induced Motions in Tall Buildings

Book Description
With ever increasing constructability capacities, engineers have found solutions to build taller and taller structures. However, the race for the sky has not only brought up new ways of building, it has also created new problems to face, namely wind-induced motions. In particular, wind loadings are now the source of vibrations in buildings, which have a direct impact on users. While in the past, strength capacities were the main concern, nowadays, human's comfort has become the one of the new primary problems engineers have to face when designing skyscrapers. Several solutions have been developed throughout the years in order to mitigate the response of a building to wind loads, one of which is the Tuned Mass Damper system. This system, which consists of an auxiliary mass added to a structure, significantly reduces motions in high-rise buildings. However, the theory is often based on a harmonic excitation of a building, which is not necessarily the exact representation of wind loads. This paper analyzes the effects of a Tuned Mass Damper on the response of a building to a saw tooth excitation with white noise, which seems to be a better approximation of how wind loads act on tall structures.

Book Description
As software skills rise to the forefront of design concerns, the art of structural conceptualization is often minimized. Structural engineering, however, requires the marriage of artistic and intuitive designs with mathematical accuracy and detail. Computer analysis works to solidify and extend the creative idea or concept that might have started o
