INFLUENCE FACTORS ANALYSIS ON ASEISMIC BEHAVIOR OF PREFABRICATED FRAME JOINTS WITH CAPACITY OF SELF-CENTERING

The precast concrete frame joint with the capacity of self-centering provided by post-tensioned steel uses the dry joint connection method. In order to research the main influence factors on aseismic behavior of prefabricated frame joints with the capacity of self-centering, all relevant references are calculated and simulated on the stage of finite element software ABAQUS with the factors of stretching control stress, the number of post-tensioned steel, and reinforcement ratio, under a monotone load and cyclic loads. The results show that: the number of post-tensioned steel has a greater influence on the aseismic behavior of a structure, and the stretching control stress has influence in a certain range, but the reinforcement ratio has a less influence, and the results have some degree of guiding significance on the popularization of a prefabricated frame.
