Summary

This chapter presents seismic vibration control of civil engineering structures. It is divided into two main sections.

The first part of the chapter deals with vibration control by seismic base isolation, whereas the second part covers

methods of response control that use passive energy dissipation, active control, semiactive control, and hybrid

control, respectively. Each part starts with a brief description of the historical development of these methods,

followed by basic principles and important issues in their implementation. Thereafter, devices used for structural

response control, their design methods, and recommended experimental procedures for verification of their

properties and analytical modeling are discussed. Various methods generally used for analysis of such structures are

then discussed in detail followed by a brief description of the implementation of these methods for various types of

structures. In addition, performance of existing structures during past earthquakes is also included, to highlight the

effectiveness of these methods during real earthquakes. Further information on the general topic of this chapter is

found in Chapter 22, Chapter 30, and Chapter 31.
