Abstract

SUMMARY In this study, different energy components in the tall reinforced concrete core-wall buildings with numerous plastic hinges over the height are investigated using nonlinear time history analysis. The effect of near-fault and far-fault earthquakes is compared. The idea of one-plastic, two-plastic, three-plastic and whole-plastic hinge approaches along the core wall is examined. The input energy, inelastic, damping, kinetic and elastic strain energy during the earthquakes are studied. The results show that a large energy quantity transfers to the structure at the arrival time of the near-fault motion pulse. Inelastic energy distribution over the height shows a considerable amount of inelastic energy dissipation occurring at the base and above the mid-height of the walls.
