Building damping device

Abstract

The invention discloses a building damping device. The building damping device comprises a damping structure. The damping structure comprises a base which is embedded into the inner central position of a certain section inside a building and a swing assembly which is hung on the base. The swing assembly comprises a swing arm which is connected with the base in a rotating mode and a pendulum bob which is mounted beneath the swing arm. The building damping device further comprises an energy dissipation mechanism which is connected with the pendulum bob. The building damping device is simple in structure, convenient to manufacture and construct, and capable of achieving the purposes of balancing the building and reducing the left-right swing scope of the building and consumed energy under the condition that earthquakes are small.

Description

technical field [0001] The invention relates to a shock absorbing device. Background technique [0002] In addition to the long-term vertical load, the building also bears the effect of wind and earthquake horizontal load. The higher the building, the more obvious the effect of this horizontal load. my country is one of the countries most severely affected by earthquake disasters in the world. According to statistics, 41% of my country's land area and 50% of cities are located in areas with an earthquake intensity of 77 degrees or more. The earthquakes of magnitude 7 or above in my country's mainland account for about 50% of the world's continental earthquakes. The death toll due to earthquake accounts for about 1 / 3 of the world's earthquake death toll. my country is facing a very severe form of earthquake disaster. [0003] my country's building structure seismic code requires that the building structure and its components must have sufficient earthquake resistance and defo...

AI Technical Summary

Problems solved by technology

The earthquake resistance of traditional building structures depends on the resistance of the structure itself. The foundation is embedded in the soil of the foundation, and the earthquake response gradually increases from the base upward. However, in order to improve the bearing capacity of the structure, the cross-sectional area of ​​the components must be increased. This approach not only leads to a heavy structure but also consumes a lot of materials. In addition, the existing building shock-absorbing and shock-isolating devices are generally high in cost and complicated in installation steps, so they cannot be widely used.
