Abstract

The invention discloses a full-assembly type self-resetting frame structure with steel strands arranged in a single-span full-length mode. The full-assembly type self-resetting frame structure comprises at least two column bodies, an H-shaped steel beam connected between the two column bodies, concrete foundations connected to the bottoms of the column bodies, beam-column connecting pieces, the prestressed steel strands and tie rods, wherein the H-shaped steel beam comprises an H-shaped main beam and H-shaped connecting short beams which are connected to the two ends of the H-shaped main beam in an assembly mode; the prestressed steel strands are tensioned between anchoring plates on the two H-shaped connecting short beams; each H-shaped connecting short beam is connected with the corresponding column body through the corresponding beam-column connecting piece; and the tie rods connect the column bodies with end plates on the beam-column connecting pieces through core penetrating holes. According to the full-assembly type self-resetting frame structure, the prestressed steel strands are independently arranged in the single-span full-length mode, full-assembly construction of the prestressed steel strands can be achieved, the tensioning quality and precision of the steel strands are ensured, the construction efficiency is improved, the labor cost is reduced, and the full-assembly type self-resetting frame structure conforms to the development trend of building structure assembly.

Description

technical field

[0001] The invention belongs to the technical field of earthquake prevention and disaster reduction of civil structures, and in particular relates to a fully assembled self-resetting frame structure with single-span and long-length arrangement of steel strands. Background technique

[0002] Through the ductility design of the traditional frame structure, the main lateral force-resisting components undergo plastic deformation to dissipate the seismic energy under the action of the earthquake. Although it can ensure that the building structure does not occur destructive behaviors that cause major loss of life, it will be difficult or impossible to repair the structure after the earthquake. Huge economic losses due to restoration. The self-resetting frame structure specifically solves the shortcomings of the traditional frame structure. In the existing self-resetting frame structures, prestressed steel strands are mostly used as the resetting elements of the st...
