Abstract: To address the pain points in the experimental teaching of engineering seismic isolation technology, such as insufficient teaching depth, and the difficulty in balancing experimental cost with engineering reality, a small-scale unidirectional double-friction pendulum bearing (UD-FPB) experimental teaching apparatus was developed. The device is equipped with a transparent viewing window and a modular quick-release structure, enabling flexible adjustment of key parameters such as bearing radius and vertical pressure load. A multi-level progressive practical curriculum links of “theoretical teaching–basic verification–comprehensive exploration–innovative design” was constructed. Through low-cycle cyclic loading tests on the bearing, the theoretical hysteretic model of the bearing was validated, and the influence laws of multiple factors on its mechanical properties were investigated. The seismic isolation effect was verified via shaking table tests. This apparatus can be applied not only to the experimental teaching of civil engineering students but also serve as a research and development carrier for postgraduates in related fields to conduct engineering practice and innovation.
