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
The advent of modern structural systems, spurred by advances in construction methodology and high strength materials, has driven the height of modern skyscrapers beyond what was once deemed possible. Although science and technology has been able to increase the strength of building materials such as steel and concrete, their material stiffness has remained virtually unchanged. The end result is a wave of taller, slender and more flexible skyscrapers that are very susceptible to wind-induced excitations. Ever mindful of the fact that human comfort levels are affected by perceived structural responses, engineers must employ various strategies to satisfy serviceability constraints. This thesis presents an overview, in addition to successful applications, of the various aerodynamic and damping modifications that are used to control wind-induced motion in tall buildings. Finally, a modified gyrostabilizer, akin to those used in luxury yachts, is proposed as a possible active control mechanism. The feasibility of this device was studied using simple statics and rigid body dynamics.
