Seismic Behavior of Resilient Rocking Steel Column Base
A resilient rocking steel column base (RRSCB) installed with composite combination disc spring (CCDS) is proposed in this paper. The restoring force model and energy calculation formulae of the RRSCB are derived by the theoretical analyses and energy conservation law, respectively. A refined finite element model validated by the cyclic loading tests is established with the aid of ABAQUS to investigate the seismic performance of the RRSCB. The results indicate that the RRSCB possesses satisfactory self-centering capability and desirable energy dissipation capacity for the design displacement. The established restoring force model and energy calculation formulae can reasonably predict the hysteretic behavior of RRSCB under cyclic loading.
