Energy Absorbing

The energy absorbing devices have been recognized as effective tools for dissipating the earthquake-induced energy during earthquakes. Several kinds of metallic-yielding, viscous and friction dampers have been proposed, tested and adopted in engineering applications in recent years. In this study, results from experimental and numerical studies of an advanced unbounded brace, or named as the advanced buckling restrained brace (advanced BRB), have been introduced. The experimental results from the component tests under cyclic loadings show that the proposed device possesses good stability and durability in mechanical behavior. Results from numerical studies of a 10-storey steel structure with proposed devices subjected to different earthquakes show that the advanced BRB can lessen the column shear forces as well as the storey drifts of the structure efficiently. Based on this investigation, the proposed isolator can be adopted as an effective tool for enhancing the seismic resistance of structures during earthquakes.
