9000OPTIMAL DESIGN AND CONFIGURATION OF SEISMIC DAMPERS

The usage of passive control devices have been increasing for structures under seismic and wind excitations. The optimal configuration of these devices will increase the safety and cost effectiveness. In this study a new reassessed algorithm is proposed that enhances the previous studies and finds more cost effective optimal configuration of dampers. In order to include the overall cost benefit, the new algorithm is updated. Particularly viscoelastic fluid dampers, which have been popular in dampers, are analyzed. The new reassessed algorithm can be adapted to other types of dampers. The results obtained from the new algorithm is compared with the studies of Ribakov and Gluck (1999), Lopez Garcia (2001), and Ribakov et al. (2001) and proven to be as effective and efficient as other algorithms or configurations. In all four examples the algorithm leads to more cost effective results which are also preferable in practical manner. For the examples conducted, the response of the structure increased just a little bit, within the limits chosen by the user, or did not increase at all. When compared to the reduction in cost, the response increase became negligible. With this algorithm it is easy to make cheaper, still efficient and effective damper configurations within the limits that can be defined by user.
