The aim of this work is to study the effect of vibration control devices on the reliability-based design of stochastic dynamical systems. In particular, structural systems under stochastic ground excitation are considered in this work. The reliability-based optimization problem is formulated as the minimization of an objective function subject to multiple reliability constraints. Probability that design requirements are satisfied within a given period of time is used as a measure of system reliability. Vibration control devices composed by hysteretic elements are considered in the present implementation. The hysteretic behavior is characterized by the Bouc-Wen type model. The optimal design problem is solved by a sequential approximate optimization strategy cast into the framework of conservative approximations. A numerical example is presented to illustrate the effect of vibration control devices on the design of a structural system under stochastic earthquake excitation.
