This study assesses the effectiveness of seismic base isolation using triple friction pendulum isolators (TFPIs) as a retrofitting strategy for a five-story steel building. This building is ...

This paper introduces a novel seismic base isolator termed the “pendulum column with vertical negative stiffness (PC-VNS),” which functions similarly to a pile foundation while incorporating quasi ...

Researchers have developed a novel negative-stiffness isolation device that offers a pioneering solution for seismic protection. The device, designed to provide multidirectional negative stiffness and ...
