Abstract

The invention discloses a column component with a built-in viscous damping geotextile. The column component comprises longitudinal bars, stirrups, the built-in viscous damping geotextile and concrete. A woven geotextile is arranged on the outer layer of the built-in viscous damping geotextile; criss-crossed PVC flexible pipes are arranged in the built-in viscous damping geotextile; the PVC flexible pipes are filled with viscous damping matter; one layer of the built-in viscous damping geotextile is wrapped on the outer surface of a steel bar cage bound through the stirrups; the built-in viscous damping geotextile and the longitudinal bars are bonded through an adhesive; and then concrete pouring is conducted to enable the column component to be a whole. Anti-seismic performance of the column is improved by means of good energy consumption performance of the viscous damping matter; and when a structure is destroyed by a strong earthquake, the epoxy resin in the PVC flexible pipes flows out to serve as an adhesive to bond cracks of the column, so that the structure has a certain self-healing property. Through the mode that the high-strength geotextile is wrapped on the steel bar cage, integrality of the column is improved, and brittle fracture of the column is effectively prevented. The geotextile attached to the steel bar cage further can share shearing force of the stirrups, so that the shearing resistant strength of the column is strengthened.

Description

technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to a column member with a built-in viscous damping geotextile. Background technique [0002] Energy dissipation and shock absorption technology is to design some components in the structure as energy dissipation components, or to set energy dissipation components in certain parts of the structure. At present, the more effective way of energy dissipation and shock absorption is to install viscous dampers. Viscous dampers are widely used in the field of civil engineering as an energy-dissipating and shock-absorbing device that does not require external energy input. However, because it is usually installed outside the structure, it is inevitably affected by temperature changes, chemical corrosion, etc., which greatly reduces the service life. Great protection. [0003] As a multifunctional composite material, geotextiles are currently applied in the field of...
