Aiming at the characteristics of prestressed fabricated frame joints, proposes a finite element modelling method based on OpenSees. Then, verify the correctness of the finite element model combining experiment of prestressed fabricated frame structure. it shows that the proposed joint finite element model can predict the seismic performance of the structure accurately. Detailed parameter analysis is performed to study the general law of seismic performance evolution of joint from five aspects, namely, prestressed tendon area, energy-dissipating tendon area, concrete strength, axial compression ratio, and tensile control stress. Analysis results show that prestressed tendon area, axial compression ratio and tensile control stress should be constrained to some extent, otherwise the performance of joint would deteriorate.
