Abstract
A fabricated intelligent joint provided with particle damping chambers for energy dissipation includes a core steel frame, an external fully-fabricated steel pipe column, a fully-fabricated annular beam-column connecting assembly, a structural health detection system and particle damping chambers. The core steel frame is located in the external fully-fabricated steel pipe column, is concentric with the external fully-fabricated steel pipe column and comprises a circular hollow steel keel and a plurality of protruding steel plate wings. The external fully-fabricated steel pipe column is formed by splicing a plurality of arc steel pipe column sheets. A space between the external fully-fabricated steel pipe column and the circular hollow steel keel of the core steel frame has the particle damping chambers installed therein and has concrete poured therein. A large quantity of spherical rubber particles is contained in the particle damping chambers.
