Damage repairing assembly type combined column with self-reset function

Abstract

The invention discloses a damage repairing assembly type combined column with a self-reset function. The combined column comprises a lower column segment connected to the upper portion of a ground beam, an upper column segment connected to the upper portion of the lower column segment and a damper connected between the lower column segment and the ground beam; the lower column segment comprises a reinforced concrete column body and a steel sleeve, wherein the lower end of the reinforced concrete column body is sleeved with the steel sleeve from bottom to top; the damper comprises a plurality of soft and rigid damping plates arranged at intervals along the periphery of the lower column segment, the soft and rigid damping plates are vertically placed, the inner ends of the soft and rigid damping plates are connected with the steel sleeve, the outer ends of the soft and rigid damping plates are connected with T-shaped connecting plate components, and the bottoms of the T-shaped connecting plate components and the ground beam are connected together; the soft and rigid damping plates are weak in strength and good in plasticity, concentrated deformation can be generated, most earthquake energy can be absorbed, during the strong shock, the e soft and rigid damping plates generate violent deformation and even are damaged, prestress applied by prestress anchor tools can help the reinforced concrete column body of the lower column segment to be reset by itself, oversize deformation is not generated, after the shock, dismounting is carried out, the damper is replaced, and in-situ rapid repairing of a house after the shock can be achieved.

Description

technical field [0001] The invention relates to an anti-seismic structure of a concrete member, in particular to a damage repairable assembled composite column with a self-resetting function. Background technique [0002] The intelligentization and sustainability of urban development pose new requirements and challenges to the industrialization of buildings and earthquake resistance of engineering structures. Among them, realizing the rapid repair of structural earthquake damage and the rapid restoration of building functions is the basic requirement and important research direction of "restorable functional city". Recoverable performance structures generally refer to building structures that can recover their performance without repair or moderate repair after the structure encounters an earthquake. The research, development, promotion and application of recoverable performance structures can not only significantly reduce direct earthquake damage losses, but also significa...
