A low-frequency system that maintains a constant degree of stiffness for isolation purposes is the conventional seismic isolation system, which depends on sliding bearings like friction pendulum isolators (FPIs). This particular system might function well in typical earthquake settings, but it might experience significant displacement for isolation when dealing with earthquakes that have strong long-period components, especially those that happen close to faults. Specific actions must be taken in order to improve isolation performance and reduce excessive reactions brought on by long-period ground motions. A slider is positioned between two sliding surfaces that can have different curves to form the double sliding isolator with variable curvature (DSIVC). When compared to a single sliding isolator of the same size, the double sliding isolator has double the displacement capacity. This higher displacement capacity allows the isolators’ manufacturing costs and installation area to be reduced while keeping their intended size. The purpose of this research is to evaluate the seismic performance of DSIVC on the Benchmark Highway Bridge. Using the benchmark problem’s evaluation criteria, the performance of DSIVC is evaluated and compared to that of a friction pendulum system (FPS). The findings suggest that DSIVC can reduce isolator displacement while maintaining the same isolator size, providing greater design freedom. Furthermore, DSIVC shows potential as an improved isolation technique capable of transforming a passive isolator into an adaptive isolator.
