Abstract Combined with the established axial restoring force model of the concrete-filled steel tube (CFST) column, the elastoplastic time-history analysis of the diagrid tube structure was carried out, and the distribution law of each energy item in the structure was studied. The distribution of hysteretic energy dissipation was analyzed in turn from the three levels of structure-member-floor, and the influence of structural dynamic characteristics and ground motion parameters on the distribution of hysteretic energy dissipation was discussed. The research shows that the structure mainly balances the earthquake input energy through damping energy dissipation and hysteretic energy dissipation. The main energy dissipation components of diagrid tube structure are inclined column and coupling beam. The hysteretic energy dissipation of the inclined column decreases with the increase of the floor and there is an obvious sudden change at the junction of the modules, so the large sudden stiffness change should be avoided in the design. The study reveals the damage mode and energy dissipation mechanism of diagrid tube structure from the perspective of energy, which provides a reference for establishing the seismic damage assessment method of the diagrid structure.
