Abstract
Existing experimental results clearly demonstrate that the structural use of conventional, that is, "passive," high-performance fiber reinforced concretes (HPFRCs) results in excellent seismic performance. By combining shape memory alloy (SMA) fibers with conventional HPFRCs, self-actuating HPFRCs were recently developed. This paper explores a novel way of using such self-actuating SMA-based HPFRCs to develop more seismically resistant and cost-effective, auto-adaptive frame buildings. A numerical investigation on the use of self-actuating HPFRCs in highly energy absorbing, replaceable, "fuse" zones is presented first. Resulting SMA-HPFRCs "fuses" can adjust their response to the level of seismic overload. A brief discussion of the possible use of such self-actuating "fuses" in auto-adaptive structures is also provided. While in an actual auto-adaptive structure "triggering" of the desired self-actuating HPFRC fuse behavior will require the use of "sensing" and control elements, this paper focuses only on the behavior of SMA-HPFRC fuses and their effect on the overall structural response.
