A large number of papers have been published on active control of structures subjected to earthquake. Most of these papers, however, are limited to describe various techniques to control the structural response under the assumption that the active control system is perfectly workable without failure. This paper presents a new analytical technique to estimate the first-passage problem of actively controlled hysteretic structures considering sensors failure probability. The proposed method is based on the stochastic equivalent linearization and iterative techniques, and also evaluated by comparing the results with those from numerical simulations.
