Viscoelastic damper used for buckling restrained braced building

Abstract

The invention relates to a viscoelastic damper used for a buckling restrained braced building. The viscoelastic damper comprises a first inner steel plate and a second inner steel plate, wherein the upper surface of the first inner steel plate is connected with a first outer steel plate by a viscoelastic material layer, and the upper surface of the second inner steel plate is connected with a second outer steel plate by a viscoelastic material layer; the first outer steel plate and the second outer steel plate are fixedly connected; a certain gap is reserved between the first inner steel plate and the second inner steel plate; a center steel plate is arranged in the gap; the left end of the center steel plate is provided with a brake block; and the left ends of the first outer steel plate and the second outer steel plate are connected with a C-shaped connecting plate. The viscoelastic damper used for a buckling restrained braced building can bear tension but can not bear pressure, is used for reducing the reaction of high-rise or super high-rise buildings under the action of wind load and earthquake and has a thorough buckling restraining function, and the problem that the original efficacy of the damper can not be performed because a connecting member possibly has a failure of buckling when the practical damper is subjected to compressive deformation can be effectively solved.

Description

technical field [0001] The invention relates to a construction machine, in particular to a viscoelastic damper for anti-buckling support type construction. Background technique [0002] Earthquake damage caused by major earthquakes that have occurred around the world in recent years has raised society's expectations for the seismic performance of buildings. The traditional seismic design is committed to ensuring that the structure itself has a certain degree of rigidity, strength and sufficient ductility, so that the designed structure "is not damaged by small earthquakes, repairable by moderate earthquakes, and not collapsed by major earthquakes". Under the action of an earthquake equivalent to the design intensity, some structural components enter an elastic-plastic state, which is easy to repair after the earthquake; under the action of a rare earthquake, although the damage is serious, the structure will not collapse, thereby avoiding casualties. However, owners have va...

Problems solved by technology

[0006] In order to solve the above-mentioned technical defects, the present invention provides a viscoelastic damper for reducing the destructive force of high-rise or super high-rise buildings under wind load and earthquake, and has a complete anti-buckling function, focusing on For the improvement of the wind and earthquake resistance of high-rise or super high-rise buildings, it effectively solves the problem that the actual damper cannot play the role of the damper due to the possible buckling failure of the connecting components when it is compressed and deformed.
