Problems solved by technology

Under the action of bending moment, the components rotate with each other, openings will be formed at the connecting section, and the mutual rotation of the connected components at the connecting surface makes the section compression area smaller, making it easier for the outer edge of the component compression area to reach the ultimate compressive strain or ultimate compressive strength, causing damage or destruction of prefabricated components, reducing the stability and service life of the structure

Abstract

The invention discloses a beam-end energy dissipation restricted prestress prefabricated concrete structure, including a precast pole, a precast beam, and an energy dissipation restricted sleeve. Theenergy dissipation restricted sleeve comprises a steel sleeve used for beam-end restriction and energy dissipation angle iron. The steel sleeve is sleeved on an end of the precast beam. An upper end and a lower end of the steel sleeve are provided with the energy dissipation angle iron. The energy dissipation angle iron is connected with the precast pole through a fastener. The precast pole and the precast beam are provided with prestressed tendon ducts. A prestressed tendon passes through the prestressed tendon ducts on the precast pole and the precast beam in sequence, and is pre-tightened,so that the precast beam, the precast pole, and the energy dissipation restricted sleeve are connected into an integrated one. The beam-end energy dissipation restricted prestress prefabricated concrete structure improves structure stability and service life.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a beam-end energy-constrained prestressed assembled concrete structure and a construction method thereof. Background technique [0002] Prestressed connection is a main connection method in prefabricated structures. In the construction process, it has the advantages of no wet operation and fast assembly speed; in terms of seismic performance, it has the advantages of high connection strength and strong self-resetting ability. Prestressed prefabricated concrete structures have been widely used. [0003] For precast concrete structures assembled by prestressing, the components are only connected by prestressed preloading. Under the action of bending moment, the components rotate with each other, openings will be formed at the connecting section, and the mutual rotation of the connected components at the connecting surface makes the section compression area smaller, ma...
