Seismic Response Analysis of Prestressed Concrete Rocking Frame

In order to investigate the seismic performance of prestressed concrete rocking frame (PCRF), a theoretical model based on rigid body is established for one-story single-span PCRF. The PCRF studied in this paper has connecting interfaces set at column feet and inner faces beam–column joints, allowing columns be uplifted with accompanying separation interface rotation beam around interface. tendons are arranged along centerline columns. connections between anchoring accomplished by prestressing tendons. consists beam, elastic governing motion equation derived numerical solution obtained. energy dissipation analyzed calculation method coefficient restitution derived. Time history analysis parameter response conducted results show that promising behavior.
