Description

Composite damping wall

Technical Field

The utility model belongs to the technical field of civil engineering structures, and particularly relates to a composite damping wall.

Background

The damper for building is a safety device which is installed on a building and used for reducing earthquake damage, is widely applied to civil buildings, industrial buildings, bridges and the like, temporarily absorbs and consumes the impact energy of the earthquake to the building structure to the maximum extent, and greatly relieves the impact and damage of the earthquake to the building structure.

Earthquake is a sudden natural disaster with extremely strong destructiveness, and along with the improvement of living standard and the development of society, the requirements of people on the earthquake resistance of building structures are higher and higher. The conventional earthquake-proof design method resists earthquake action by increasing the structural strength, namely, the earthquake energy is stored and consumed by utilizing the structure by means of measures such as adjusting the cross section of a component, adding reinforcing bars and the like, so that the earthquake-proof fortification requirements specified in the specification are met. Because the intensity and the characteristics of the earthquake motion possibly encountered by the structure in the future cannot be accurate, the earthquake resistance of the structure is difficult to have self-adjusting and controlling capacity, and the structure is difficult to meet the comprehensive requirements of economy, safety, comfort and reliability. People cannot make advance predictions about natural disasters such as earthquakes.

At present, the earthquake-resistant design specifications of various countries take 'major earthquake is not over, middle earthquake is repairable, and minor earthquake is not bad' as an earthquake-resistant design principle, and take the protection of the structure from damage and the protection of life safety as main targets. The traditional earthquake-resistant structure resists earthquake by enhancing the structural strength, simultaneously allows the structural member to enter an inelastic state during the earthquake, has certain ductility, consumes earthquake energy at the cost of damage of the structure, lightens earthquake reaction, is applied to mechanical, vehicle, aerospace and military engineering as an excellent energy-consuming and vibration-absorbing (vibration-absorbing) structural member, is introduced into industries such as buildings, bridges, railways, power plants, steel plants and the like for resisting vibration caused by the earthquake, wind vibration or other external loads in the 70 s, and achieves good effects.

However, the existing damper for building has many defects, such as single function of the existing damper product, various construction difficulties of the connection welding seam between the damper and the embedded part, and increased building decoration work caused by the installation of the damper. Therefore, the composite damping wall is provided for improving the energy consumption of the damper, ensuring the construction quality and reducing the construction difficulty.
