Abstract

This chapter presents an energy-based procedure for the design of supplemental damping. The average energy dissipated pear cycle at each interstory of the framing system is used as the response parameter to be reduced. The response is obtained from a stochastic approach using the equivalent linearization method and the transfer-matrix method. As illustrative example, a building with asymmetries in-plan and in-elevation subjected to bidirectional ground excitation is considered. In this example, it is observed that the proposed energy-based procedure produces better designs in terms of the optimal placement and the amount of damping required to reduce the structural response. It is concluded that the placement of a small amount of dampers, optimally located in the building, can diminish its structural response in an efficient and economical manner leading to structures with diminished hysteretic energy dissipation and consequently reduced structural damage.
