Paper Abstract

Characteristics of piezoelectric dampers built with piezoelectric materials were investigated as part of a smart structural system for buildings. Piezoelectric materials can be applied not only to the sensors and the actuators, but also to the dampers. Here, first the damping mechanism and the complex stiffness for a piezoelectric damper were derived from the piezoelectric equations. Then, based on the complex stiffness and Biggs's formula, an equation used to evaluate the damping performance for building structures with piezoelectric dampers was derived. Finally, to determine the applicability and availability of piezoelectric dampers, the habitability of a building with piezoelectric dampers to strong wind was investigated for a high-rise steel apartment building. The results show that piezoelectric dampers enable high-rise apartments of practical dimensions to satisfy H-2 grade habitability.
