Abstract
In order to research the self-centering capacity of prefabricated frame joints, this paper designed analysis models of prefabricated frame joint with the finite element software ABAQUS, contrastively analyzed seismic behavior of joint applied pretention and joint without pretention. Joint applied pretention is found to have better self-centering capacity. Then the paper calculated and analyzed the factors of stretching control stress, number of post-tensioned steel. The results show that number of post-tensioned steel has a greater influence on the seismic behavior of the structure, and the stretching control stress has influence in a certain range. The results have some degree of guiding significance for the popularization of prefabricated frame.
