Abstract

The invention discloses a self-reset viscous-elastic damping wall. The wall comprises a double T-shaped steel box, a T-shaped steel plate, a left cover plate and a right cover plate, wherein the double T-shaped steel box comprises a lower flange plate and two box web plates; a steel plate web plate is arranged between the two box web plates of the double T-shaped steel box, the upper end of the steel plate web plate extends from the double T-shaped steel box and is fixedly connected with an upper flange plate, the steel plate web plate and the upper flange plate form the T-shaped steel plate; the left cover plate and the right cover plate are arranged on the left side and the right side of the steel plate; clearances are arranged between the steel plate web plate and the two box web plates respectively, and part of the clearance is filled with a viscous-elastic material, and shape memory alloy stranded lines in parallel with the box web plate are arranged on the upper side and the lower side of the viscous-elastic material in the clearances. The energy dissipation is good, the performance is stable, the construction is simple, the processing and manufacturing is convenient, relatively more using space for building structures can be provided, the wall is convenient to mount and maintain and has certain self-set function.

Description

technical field [0001] The invention belongs to the technical field of anti-vibration and vibration reduction of civil engineering structures, and in particular relates to a self-resetting viscoelastic damping wall. Background technique [0002] Viscous damping wall energy dissipation and shock absorption control technology is an emerging anti-seismic vibration reduction technology, which has stable performance, simple technical conditions, and does not affect the use of buildings. It is mainly used in frame structures and other high-rise buildings. Wide application prospects. Traditional viscoelastic damping walls rely on the shear hysteretic energy dissipation characteristics of viscoelastic materials to provide additional stiffness and damping to the structure, reduce the dynamic response of the structure, and achieve the purpose of vibration reduction, ensuring that the structure will not collapse in a large earthquake, but the shock The post-repair cost or the cost of ...
