| Abstract |
Structural performance of the seismic devices made by steel bar and high performance fiber reinforConcrete is one of the principal materials for the structures and it is widely used all over the world. While advanced technologies of concrete have been recently focused especially on developing high performance concrete in which possess high compressive strength and durability, such concrete shows extremely brittle failure under shear and tension. To improve such a poor properties, high performance fiber reinforced cement composites(HPFRCC) has been developed. The advantages of the HPFRCC damper 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 HPFRCC are applied to the damper. It means cementitious seismic damper for structural control is available, which has much merit in performance and cost. |
