Development of Electromagnetic Friction Dampers for Improving Seismic Performance of Civil Structures
… to extreme natural events such as earthquakes. Friction is one of the most reliable mechanisms of energy dissipation that has been utilized extensively in friction dampers to improve seismic performance of civil structures. Friction dampers are well-known for having a highly nonlinear hysteretic …

Semi-active control of elastic and inelastic building structures with piezoelectric friction dampers
… devices.</p> <p>In this study, a piezoelectric friction damper (PFD) was first introduced with its clamping force regulated by piezoelectric stack actuators. A new semi-active control algorithm, which consists of Coulomb friction, viscous and non-linear Reid damping mechanisms, was proposed to …

Energy Redistribution with Controllable Binary State Latch Element
… device can be viewed as variable semi-active dampers such as magnetorheological (MR) and piezoelectric friction dampers. The distinct difference between other semi-active dampers and our latch device is that other semi-active dampers can provide continuous resistance according to the amount of …

Use of Permanent Magnets to Improve the Seismic Behavior of Light-Framed Structures
… magnets, incorporated in the form of passive friction dampers, to dissipate a part of input energy induced due to strong ground motions, thereby reducing the inelastic energy dissipation demand of the lateral load resisting system. The force of attraction between the permanent magnet and …

Enhancement of the Sliding Hinge Joint Connection with Belleville Springs
… sliding. This may give better control of the frictional capacity and increase the residual joint strength. • Determining the bolt behaviour, sliding shear capacity, and hysteretic component force-displacement behaviour for the friction component with various options of Belleville springs, …
