An integrated vibration and vibration control structure and design method for a subway superstructure

Abstract

The invention provides a vibration and earthquake integrated control structure for buildings above a subway. The vibration and earthquake integrated control structure comprises a full-layer coupling beam additionally arranged in a building basement, a building structural beam below the full-layer coupling beam, and a vibration isolation layer arranged between the full-layer coupling beam and the building structural beam. The vibration isolation layer comprises light spring vibration absorbers and viscous dampers, wherein the light spring vibration absorbers are arranged between upper buildingsupporting pillar bodies and lower building supporting pillar bodies which are formed by breaking building supporting pillars between the full-layer coupling beam and the building structural beam, andthe viscous dampers are arranged between the full-layer coupling beam and the building structural beam. A complete and feasible quantitative analysis integrated design method is established based onthe vibration and earthquake integrated control structure, the vibration and earthquake integrated control structure and the design method can meet the requirements for subway vibration control operation and earthquake fortification at the same time, and replacing and maintenance are convenient.

Description

technical field [0001] The invention relates to a vibration-seismic integrated control structure and design method of a subway superstructure, belonging to the technical field of engineering vibration reduction and isolation technology. Background technique [0002] For subway superstructure, adjacency, and cross-construction projects, the operation of the subway will have adverse effects on the buildings. It is necessary to isolate the vibration of the subway superstructure. Generally, a vibration isolation layer is required, and rubber shock absorbers are often used to reduce vibration. However, when the building has space constraints and cannot set up a vibration-isolation layer, there is currently no uniform standard and design process, and most of them rely on experience to design vibration-isolation schemes, or directly apply schemes similar to existing projects. . Traditional design methods have the following disadvantages: [0003] (1) Misunderstandings about rubbe...

AI Technical Summary

Problems solved by technology

[0005] In view of the adverse effects of subway operation on buildings in subway superstructure, adjacency, and cross-construction projects, and the situation that the upper structural space of the building is relatively limited and it is impossible to install a vibration isolation layer, the invention proposes a subway superstructure Building vibration-seismic integrated control structure and its vibration reduction and anti-seismic design method, in which a partition layer is set in the basement of the building, the structure and technology can simultaneously meet the building vibration control requirements without changing the design parameters of the upper structure of the building And anti-seismic fortification under rare earthquakes to ensure the normal use of buildings and the safety of personnel under earthquakes
