Abstract
ABSTRACT To achieve seismic resilience, this work investigates a new type of self-centering beam-column joint equipped with arc-shaped steel plate dampers. Six joint specimens, without or with steel plates of different arc radiuses and chord heights, are experimentally studied. Tested specimens exhibit distinct flag-shaped hysteresis loops, indicating stable moment bearing capacity and rotation stiffness, energy dissipation capacity, and self-centering capability. A comprehensive simulation method for the joint is introduced and validated by tests. Then, numerical parametric analysis is carried out to further evaluate the influence of other parameters including plate thickness, steel property, flexibility in connection, and initial prestressing force.
