Optimal Seismic Performance of Friction Energy Dissipating Devices
Abstract eng: Friction-based passive energy dissipation devices (or dampers) are known to be very effective for controlling the seismic response of multistory buildings. The preliminary design of these devices is based on numerical simulations wherein sliding friction is modeled with Coulomb friction having a constant coefficient of friction. However, the basic laws for sliding materials and experimental investigations show strongly non-linear relationship between dry friction and sliding velocity, which includes stiction and Stribeck effect. This paper investigates energy dissipation devices in which the friction model considers the stiction and Stribeck effects. The optimal seismic performance of friction devices to reduce the response behavior of frame buildings has been numerically investigated.
