Magnetorheological (MR) dampers are devices that can be use d for vibration re- duction in structures. However, to use these devices in an ef fective way, a precise modeling is required. In this sense, in this paper we consider a modified p arameter identification method of large-scale magnetorheological dampers which are repre sented using the normalized Bouc- Wen model. The main benefit of the proposed identification alg orithm is the accuracy of the parameter estimation. The validation of the parameter iden tification method has been carried out using a black box model of an MR damper in a smart base-isol ated benchmark building. Magnetorheological dampers are used in this numerical plat form both as isolation bearings as well as semiactive control devices.
