Shape memory TiNi wire reinforced/acrylic matrix smart composite has been studied by the authors to enhance the strength and fracture toughness of the machinery components by using a shape recovery force associated with inverse phase transformation of shape memory alloy (SMA). It is also well known that SMA shows the remarkable changes of stiffness and damping between lower temperature martensite and upper temperature austenite phases. Therefore, in the present paper, the authors try to study the active control of deflection and vibration of the base floor plate of the smart bridge model by using direct heating method for the embedded TiNi wires in the composite. The effect of heating time and prestrain of SMA wire on the deflection and damping of the TiNi/acrylic composite structure are experimentally investigated.
