The multifunctional vibration–absorption RC megaframe structures, which act as tuned mass dampers, base isolators and damping energy‐dissipaters, are presented. The proposed systems are essentially different from the normal megaframe structures in earthquake responses, failure mechanism, and theoretical model of seismic design. The elasto‐plastic dynamic analyses show that the earthquake responses of the multifunctional vibration–absorption RC megaframe structures decrease significantly in comparison with the normal megaframe structures, namely 60–80 per cent decrease of the earthquake responses of the major frames and 70–90 per cent decrease of the ones of the minor frames.
