Building Control with Passive Dampers Optimal Performance-based Design for Earthquak





Preface

The concept of performance-based design is well accepted in the current structural

design practice of buildings. In earthquake-prone countries, the philosophy

of earthquake-resistant design to resist ground shaking with sufficient stiffness and

strength of the building itself has also been accepted as a relevant structural design

concept for many years. On the other hand, a new strategy based on the concept

of active and passive structural control has been introduced rather recently in order

to provide structural designers with powerful tools for performance-based design

(Kobori, 1993; Housner et al., 1994, 1997; Soong and Dargush, 1997; Kobori

et al., 1998; Hanson and Soong, 2001; Casciati, 2002; Johnson and Smyth, 2006).

Passive control systems are often used to meet flexibly the requirements posed by

this performance-based design. However, the structural engineers do not appear

to have the tools for the optimal selection and placement of these passive control

systems.
