Describes important principles for dealing with the damping of structures to aid in the analysis and design of supplemental damping to mitigate seismic effects. This text also examines limitations and the problem of damping and stiffness nonlinearity, which may not be approximated with sufficient accuracy using the simplified approaches.

This book provides principles and guidelines to help engineers design supplemental damping devices to reduce earthquake-induced structural vibrations-especially when the level of damping is high or when nonlinearities are important design issues. It tackles limitations of conventional design practice and explores how to improve them to handle enhanced damping. The book reviews structural dynamics theory, introduces design principles for commonly used dampers, and explores more detailed procedures based on the classification of specific damping devices according to their linearity. It helps engineers select the most effective type of damper and determine the amount and configuration of damping under given working conditions.
