Abstract

Abstract

The numerical model in OpenSees was established based on the previous research on the new prestressed prefabricated concrete frame connection strengthened by energy dissipaters. Firstly, the numerical results were compared with experimental results, which demonstrated that the proposed numerical model could simulate the bearing capacity and self-centering characteristics of the connection well. Secondly, the bearing capacity and energy dissipation capacity of the new prestressed prefabricated concrete frame connection were found to increase with the increase of the yield stress of energy dissipater, but the prestressed prefabricated concrete frame connection with energy dissipaters with lower yield stress could dissipate the energy earlier. Finally, compared with the prestressed prefabricated concrete frame connection installed with mild steel dampers, the prestressed prefabricated concrete frame connection installed with aluminum alloy dampers sustained similar bearing capacity but had lower connection's stiffness and yielding force.
