Self-actuating fiber composites for auto-adaptive structures
This paper explores a novel approach in developing auto- adaptive, High-Performance Fiber Reinforced Concrete (HPFRC)-based composite structures. This is achieved through the selective use of hybrid, self-actuating, Shape Memory Alloy-HPFRC composites (SMA-HPFRCCs). Previous use of `passive' HPFRCs in seismic retrofit and new construction resulted in excellent seismic performance. By combining `passive' FRC fibers with continuous or discontinuous SMA fibers, self-actuating SMA-HPFRCCs that can change their stress-strain response during loading, were recently developed. The paper presents results of a numerical investigation on the use of such SMA-HPFRCCs to develop highly energy absorbing, replaceable, `fuse' zones that adjust their response to the level of overload, and thus optimize overall system response to the different levels of seismic excitations.
