Recoverable fully-prefabricated segment assembled hollow pier based on ECC-mild steel collaborative energy consumption and assembling method thereof

The invention discloses a recoverable fully-prefabricated segment assembled hollow pier based on ECC-mild steel collaborative energy consumption and an assembling method thereof. The recoverable fully-prefabricated segment assembled hollow pier comprises a pier bottom hollow segment, a pier body standard hollow segment, an energy consumption device, a cover beam and a bearing platform. The energy dissipation device is composed of upper and lower slotted steel plate assemblies arranged at intervals, energy dissipation soft steel and a plurality of prefabricated ECC blocks. The upper and lower slotted steel plate assemblies are connected with the pier bottom hollow section and the bearing platform through bolts correspondingly. The pier bottom hollow section, the pier body standard hollow section and the bent cap are connected through high-strength finish rolling twisted steel penetrating through the thin wall. In addition, the bearing platform and the cover beam are connected through unbonded prestressed tendo
