Development and verification of a new OpenSees element model for a two-stage friction pendulum bearing

Abstract Bridges play a critical role in transportation infrastructure, and ensuring their safety is a key concern for structural engineers. Various seismic isolation techniques have been introduced to mitigate the impact of earthquake forces. The unavailability of novel isolation elements in commer...
