Abstract
Three model specimens of alkali-activated slag concrete filled steel tube (AAS-CFST) with different axial compression ratio and steel ratio were designed and tested in the present study. The seismic performance of the structures were evaluated by testing them with combined lateral constant compression and vertical cyclic loads. The structural performance, such as the testing observations, hysteretic behavior, skeleton curve, stiffness degradation, energy dissipation capacity and ductility performance was discussed in detailed. The results show that all the specimens’ damage were bending deformation mode, and the hysteretic curves are relatively smooth. Test data indicated that increased the axial compression ratio improved the load bearing capacity, initial stiffness.
