Seismic Performance Evaluation of Building-Damper System under Near-Fault Earthquake

open access: yesShock and Vibration, 2020
The building-damper system designed by a seismic code is usually considered to be able to withstand the attack of strong earthquakes. However, near-fault earthquakes, especially those with the forward-directivity effect, might cause early and unexpected ...

Mechanism and experimental validation of innovative self-centering conical friction damper

open access: yesStructural Control and Health Monitoring, 2020
Past earthquakes have shown that traditional structural design relies on the component ductility to dissipate the earthquake energy. This has led to significant damage for the structure. Innovative energy dissipation devices have been developed in the past to dissipate the earthquake energy.
