For instance, more than 100 RC piers had been demolished because they suffered from significant permanent drift ratio (i.e., 1.5) soon after the 1995 Kobe earthquake [1]. Lessons drawn from these events enlighten us that only satisfying the seismic ductility demand will not be adequate for engineering structures simply because their residual deformation following earthquake still significantly jeopardizes their typical functionality [2]. To assure service operation with the structures right after earthquakes, resilient capacity is being paid much more focus in the seismic codes of numerous countries (e.g., US, Japan, and New Zealand) [5]. Rocking element, as a resilient structural member, has been attracting extensive experimental and numerical studies [60]. For instance, the traditional post-tensioned (PT) rocking bridges happen to be studied by shake table tests not too long ago [113]. These research revealed that these self-centering Cyclopamine supplier bridge systems were capable of sustaining a big drift ratio of up to 10 but only experienced modest residual drift ratio (i.e., 0.5) with non-critical damages [14]. Subsequently, a series of innovative devices had been presented to further boost the selfcentering and energy dissipation capacities of your rocking piers below intense earthquake events [158]. Despite the fact that the PT tendons with each other with several energy dissipaters can supply fantastic recoverability and power dissipation capacity for the rocking pier [19,20], the energy dissipater may be broken and hence needs to be replaced immediately after earthquakes, major to compromised rescue efficiency. Additionally, some harm patterns such asMaterials 2021, 14, 6500. 10.3390/mamdpi/journal/materialsMaterials 2021, 14,two ofrelaxation and environmental corrosion on the PT tendons are hard to repair. In this regard, shape memory alloy (SMA) that’s characterized by super-elasticity has been lately thought of for numerous devices (i.e., SMA tendons, bars, and springs) utilized in resilient bridge structures [211] too as other varieties of structural systems [329]. In distinct, a bridge method with SMA-washer primarily based rocking pier was recently proposed to achieve self-centering functionality through earthquakes [40]. The SMA washers supplied restoring force for the RC pier, which can eradicate some inherent shortcomings, which include corrosion and relaxation, induced by the PT Chelerythrine Epigenetic Reader Domain tendon. Nonetheless, the reinforcing steel embedded within the plastic hinge with the pier was nevertheless vulnerable to yield as a result of massive bending moment during severe earthquakes. Varela and Saiidi [41] integrated SMA bars with elastomeric rubber bearing to replace the traditional plastic hinge of your RC pier. The test results indicated that, except for the bucking on the SMA bars, the RC pier seasoned practically no damage even un.
