Abstract: To meet the needs of the seismic performance of concrete at the node joints of assembled buildings, a self-balancing prestressing hollow bar was used to realize the effect of pre-stressing the short rod at the joint position. According to the force balancing mechanism, pressure was applied to the steel rod inside the structure, which led to the coordinated tension in the steel tube outside the structure to achieve the design. After pre-stressing and locking by the nut, bury the rod into the concrete of the joints of the assembled nodes, pour the early-strength grout, and wait for the consolidation to reach the predetermined level. Strength-releasing reaction rods, relying on the self-anchoring of the bond between the external threaded structure and the concrete to achieve the pre-stress applied to the joint concrete. The stress changes and losses in the tensile and static relaxation phases of the rod were investigated, and the tensile and static relaxation phases of the rod were verified. The validity of stress storage from completion until release was verified by analyzing parameters such as stress distribution and prestressing losses after the rod was released. The mechanism and effectiveness of stress transmission after application for odal concrete and the analysis of stresses in prestressed concrete members using finite element method distribution pattern. The pre-stressing hollow bar technology acting on the assembly nodal joints concreted has high seismic and energy-consuming capacity for assembly building the realization of high seismic performance of nodal concrete provides a new technical approach.

Key words: self-balancing prestressed hollow bar, joint concrete, stress distribution, prestress loss, finite element
