摘要：
To further investigate seismic performance of self-centering steel frame infilled with butterfly-shaped steel plate wall, two full scale specimens with different plate thickness were designed and tested under quasi-static cyclic loading protocol. According to the measured test data, the specimens' initial elastic lateral stiffness, hysteretic behavior, loading-carry capacity, energy-dissipation ability and self-centering function were studied. The results showed that the self-centering steel frame infilled with butterfly-shaped steel plate wall can effectively realize concordance and unification between self-centering function and energy-dissipation capacity; through reverse loading, the anti-compression strength of the thicker steel plate is increased and the plate restricts the system's reset function; when two specimens' story drift angles reach 2%, their residual story drift angles increase with increase in plate thickness, but they are less than 0.5% except the specimen SC-6 being pulled in unloading direction, tow specimens meet repairable requirement under moderate earthquake and the difficulty of repair is greatly reduced; when two specimens' story drift angles reach 3%, their residual story drift angles slightly increase, and their load-bearing capacity also rises, so this structure can effectively control residual deformation, and have the anti-collapse capacity under rare earthquakes. © 2019, Editorial Office of Journal of Vibration and Shock.
