摘要

Structural performance of the vibration control elements made by steel bar and advanced fiber reinforced cementitious composites was experimentally observed. These vibration control elements will be applied for reducing damage as well as response of RC structures under the performance based design system. Since stiffness of RC structures is relatively higher than that of steel structures, stiffer vibration control elements compared to the conventional one mainly applied for steel structures are required for reducing the seismic response of RC structures drastically. The advantage of the vibration control elements is selective structural performance, strength, stiffness, and ductility, by changing configuration, bar arrangements and type of materials used. The experimental results indicate that elemental ductility is much increased with decreasing damage when the advanced cementitious composites are applied to the vibration control elements. It means cementitious damper for structural control is available which has merit in performance and cost.
