Abstract
The present disclosure relates to an optical-fiber-embedded and FRP-wrapped SMA composite bar with force sensing, stress driving, and structural reinforcement integrated. The surface of the plain round Fe-SMA bar is provided with a groove in advance for implantation of the sheathed optical cable such that the bar has a self-sensing function. The plain round Fe-SMA bar having a shape memory effect is used as a steel core, so it has the characteristic of self-tensioning; an FRP wrapping layer prevents corrosion of the plain round Fe-SMA bar used as the core and prevents fracture of the sheathed optical cable, thus improving the durability of a prestressed bar structures on the outer surface of the FRP wrapping layer may provide sufficient engaging force and anchoring effect, reducing loss of prestress due to friction and the like.
