Vibration-control structures absorb seismic energy into the vibration-damping members to suppress shaking and prevent damage to the building's framework, a need that has increased in society due to the extensive damage caused by earthquakes in the past. To maximise the effectiveness of vibration control structures, seismic energy must be efficiently transferred to the damping members. The design of the joints is very important, because if the joints connecting the vibration-damping members to the framework are broken or the mechanism is not designed to transfer energy easily, the vibration control will be less effective.
However, the history of vibration control structures is relatively new and surprisingly little research has focused on their framework and connections.The laboratory will contribute to the establishment of design and evaluation methods by targeting steel-framed vibration-control structures and elucidating the behaviour of the framework and joints from experiments and analysis.
